In the triangle, we will use the Law of Cosines to find the value of angle q. angle q in the triangle is approximately 61.2° (rounded to one decimal place).

The Law of Cosines is a mathematical formula used in trigonometry to find the length of a side or an angle in a triangle.

The formula can be used to find the length of a side or an angle in a triangle, given the length of the other sides and angles.

The Law of Cosines is particularly useful when only two sides and the angle between them are known, or when only two angles and the side between them are known.

To use the Law of Cosines, you need to identify the sides and angles that you know and plug them into the formula. Then, you can use algebra to solve for the unknown side or angle.

The Law of Cosines is related to the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

The Law of Cosines can also be used in three-dimensional geometry to find the distance between two points in space.

The Law of Cosines is a useful tool in many fields, including engineering, physics, and computer graphics, and is widely used in solving geometric problems.

In this triangle, we have x = 66.1 cm, y = 22.8 cm, and angle f = 23.3º. We want to find angle q, which is opposite side x.

We can use the Law of Cosines to find the value of cos(q), and then use the inverse cosine function to find the value of q in degrees.

cos(q) = (x² + y² - x²)/(2xy)

cos(q) = (66.1² + 22.8² - 22.8²)/(2 * 66.1 * 22.8)

cos(q) = 67.8664/150.6448

cos(q) = 0.449

q = cos⁻¹(0.449)

q = 61.2°

Therefore, angle q in the triangle is approximately 61.2° (rounded to one decimal place).

The answer for lateral surface area of the Triangular prism is 180 cm²

Any solid object's lateral area can be calculated using the lateral area formula. Any figure's lateral area only includes the non-base faces. Calculating the lateral surface area of various forms, such as the cuboid, cube, cylinder, cone, and sphere, is made easier using lateral area formulas.

The lateral area for a triangular prism

A triangular prism's lateral area is equal to the sum of its side faces' areas (which are 3 rectangles). Specifically, it is the total surface area less the surface areas of the two bases. Additionally called the lateral surface area (LSA). Due to the two dimensions involved in its calculation, we measure it in square units.

The total of the three regions is the triangular prism's lateral area. Consequently, the triangular prism's lateral area formula is

Triangular prism lateral surface area (LSA) = ah + bh + ch (or) (a + b + c) h.

We are aware that the perimeter of the base is (a + b + c) (triangle). Hence,

Triangular prism's lateral surface area (LSA) is equal to the product of the base's perimeter and the prism's height.

base perimeter × height

Explanation

The Given Image of the solid is Matching to a prism.so we are calculating the lateral surface area of the prism

The dimensions of each base are:

a = 5cm

b = 4 cm

c = 3 cm

The height of the triangular prism = 15cm.

Thus, the lateral area of triangular prism = (a + b + c ) h

= (5 + 4 + 3) 15

= (12) 15

= 180 cm²

Answer: The lateral area of the given triangular prism = 180 cm²

This means x = 5a pairs up with y = 0.

=========================================================

Explanation:

The two lines have the same x-intercept, which means they cross the x axis at the same location. This is the solution to the system since this point is on both lines simultaneously.

To find the x-intercept, plug in y = 0 and solve for x.

(1/5)x+4y = a

(1/5)x+4*0 = a

(1/5)x = a

x = 5a

We don't know the value of 'a', so we cannot determine the numeric value of x.

The x-intercept is located at (x,y) = (5a,0) and this is the solution to the system.

The series for this problem is absolutely convergent, as the limit assumes a value lower than 1.

The infinite series for this problem is defined as follows:

[tex]\sum_{i = 1}^{\infty} \frac{1}{n!}[/tex]

Hence the general term is given as follows:

[tex]a_n = \frac{1}{n!}[/tex]

The limit is given as follows:

[tex]L = \lim_{n \rightarrow \infty} \left|\frac{a_{n + 1}}{a_n}\right|[/tex]

The (n + 1)th term is given as follows:

[tex]a_{n + 1} = \frac{1}{(n + 1)!}[/tex]

The factorial can be simplified as follows:

(n + 1)! = (n + 1) x n!.

Hence the limit will be calculated of:

1/[(n + 1) x n!] x n! = 1/(n + 1).

The result of the limit is given as follows:

[tex]L = \lim_{n \rightarrow \infty} \frac{1}{n + 1} = 0[/tex]

As the limit assumes a value of zero, the series is absolutely convergent.

The value of x is -20 and can be calculated using basic proportionality theorem.

The Basic Proportionality Theorem, often known as the Thales Theorem, was developed by the well-known Greek mathematician Thales.

Basic Proportionality Theorem asserted that the ratio of any two related sides is always the same for any two equiangular triangles.

Thales provided the basic proportionality theorem based on this idea (BPT). Similar triangles have introduced this idea before. If two triangles resemble one another, then

The corresponding angles of both triangles are equal.

The corresponding sides of both triangles are proportional to one another.

Since the ratio of other side pair is 1:1, similarly 4x+20 = 3x

20 = 3x-4x

20 = -x

x = -20

Therefore, the value of x is -20

Answer:  In the month of October, the animal shelter saved 92 animals.

Step-by-step explanation: In the month of October, the animal shelter saw an increase of 15% of animals being saved from the previous month. To calculate this increase, we can use the formula:

increase = (original number) x (percent increase)

In this case, the original number is 80 (the number of animals saved in September) and the percent increase is 15%. So:

increase = 80 x 0.15 = 12

This means that in October, the animal shelter saved an additional 12 animals beyond the 80 animals that were saved in September. To find the total number of animals saved in October, we add this increase to the original number:

animals saved in October = 80 + 12 = 92

So, in the month of October, the animal shelter saved 92 animals.

Answer:

2) Acute triangle, isosceles

3) Both are 65 degrees

4) (diagram)

5) a) both 25 degrees

b) midpoint

Step-by-step explanation:

2) If you're struggling search up "draw a triangle" and you'll find a website that will draw it for you. It will help you get an idea of it looks like and its nature.

3) We know that sides AB and AC are 5cm. So this triangle is an isosceles which makes the 2 remaining angles equal (if you draw a diagram it will be clear)

So:

180-50/2 = 65

ABC and ACB = 65 degrees each

4) Construct the line AH down the middle like in the diagram I drew.

5) a) Since AH is a straight line, we know that the angle AHB will be 90 degrees. After question 3 we also know that angle ABH is 65 degrees.

BAH = 180-90-65

BAH = 25 degrees

CAH = 50 - 25

CAH = 25 degrees

b) AH is the midpoint for BAC because the 2 segments formed are both 25 degrees.

 (√7)^3  is equal to 7^(3/2)

The Power of a Power Property

The Power of a Power Property states that when you have a base raised to an exponent, and that base is also raised to an exponent, you can simplify the expression by multiplying the exponents.

For example, (a^x)^y = a^(xy)

In the case of square root of 7^3, the expression (√7)^3 can be written in the form of base and exponent, where the base is √7 and the exponent is 3.

Now, we can use the Power of a Power Property to simplify the expression, by multiplying the exponents.

So, (√7)^3 = (7^(1/2))^3 = 7^(1/2 * 3) = 7^(3/2)

This means that the square root of 7^3 is equal to 7^(3/2) because the Power of a Power Property allows us to simplify the expression by multiplying the exponents.

It's worth noting that the square root of 7^3 is the same as taking the cube root of 7^3, which is 7^(3/3) = 7^1 = 7.

Answer: Fall Out Boy's service is cheaper than Five Seconds of Summer's service.

Step-by-step explanation: The cost of Five Seconds of Summer's tutoring service can be represented by the equation:

C = 5 + 5h

where C is the total cost and h is the number of hours.

The cost of Fall Out Boy's tutoring service can be represented by the equation:

C = 9 + 3h

To compare the cost of the two services, we can use the substitution method. We can set the number of hours (h) equal to a variable and substitute that variable into the equation for both services.

For example, if we set h = 4 (4 hours of tutoring), we get:

C(Five Seconds of Summer) = 5 + 5(4) = 25

C(Fall Out Boy) = 9 + 3(4) = 21

The cost of Fall Out Boy's service is $21 and the cost of Five Seconds of Summer's service is $25. Therefore, Fall Out Boy's service is cheaper for 4 hours of tutoring.

We can also graph the cost of the two services on a coordinate plane. The x-axis represents the number of hours and the y-axis represents the cost. The equation for Five Seconds of Summer's service would be y = 5 + 5x and the equation for Fall Out Boy's service would be y = 9 + 3x
