What is Law of Cosines?

The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:

c² = a² + b² - 2ab cos(C)

where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.

Given data ,

Let the triangle be represented as ΔXYZ

And , the measures of the sides of the triangle are

z = 75 inches

x = 26 inches

And , the measure of ∠Y = 135°

We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.

The Law of Cosines states that:

c² = a² + b² - 2ab cos(C)

where c is the side opposite angle C, and a and b are the other two sides.

In this case, we want to find the length of side y, which is opposite angle Y. So we can write:

y² = x² + z² - 2xz cos(Y)

Substituting in the given values, we get:

y² = 26² + 75² + 2(26)(75) cos(135°)

Simplifying, we get:

y² = 676 + 5625 - 2925√2

y² ≈ 9163

Taking the square root of both sides, we get:

y ≈ 95.76

Rounding to the nearest inch, we get:

y ≈ 96 inches

Hence , the length of y, to the nearest inch, is 96 inches

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6

Answers

Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)

by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.

Now just simplify the right side to get -25 + 11 or -14.

So f(-5) = -14.

There are 100 cookies and 80 brownies on a dessert table at a restaurant. Of these desserts, 12 cookies and 24 brownies contain nuts. What percentage of these desserts contain nuts?

Answers

Answer:

20%

Step-by-step explanation:

Total number of desserts: 100 + 80 = 180

Number of desserts that contain nuts: 12 + 24 = 36

What percentage is 36 of 180?

To find what percentage a part is of the whole, divide the part by the whole and multiply by 100%.

percent = 36/180 * 100% = 0.2 * 100% = 20%

Answer: 20%

A line has a slope of 6 and passes through the point (1,4). What is its equation in
slope-Intercept form?
Write your answer using Integers, proper fractions, and improper fractions in simplest form.
y-x-O

Answers

The slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.

The point that the line passes through is:

(1, 4)

The slope of the line is:

m = 6

The slope intercept form of the line is:

y - y₁ = m (x - x₁)

Substitute the values in the equation, we get that:

y - 4 = 6 ( x - 1)

y - 4 = 6 x - 6

y = 6 x - 6 + 4

y = 6 x - 2

Therefore, we get that, the slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.

Ana went to a book store and bought a pen and pencils and the total money she spent is $850 and a pen cost $150 and a pencil cost $100 what are all the possible purchases that she could have made.

Answers

Answer: So there are three ways...

$850=150(1)+100(7)

$850=150(3)+100(4)

$850=150(5)+100(1)

Step-by-step explanation:

The equation is 150x+100y=850 where x and y are any whole number of items that she was able to purchase with $850

So there are three ways...

$850=150(1)+100(7)

$850=150(3)+100(4)

$850=150(5)+100(1)

These are the purchases where x is pens and y is pencils

Find the length of the third side. If necessary, write in simplest radical form. sdquare root of 58 8

Answers

Answer:

√122

Step-by-step explanation:

Find the length of the third side. If necessary, write in simplest radical form. square root of 58 8

let the given sides be;

Hypotenuse = x

Adjacent = √58

Opposite = 8

Using pythagoras theorem;

hyp^2 = opp^2 + adj^2

x^2 = (√58)^2+8^2

x^2 = 58 + 64

x^2 = 122

x = √122

Hence the length of the unknown side is √122

A container can hold three orange slices. If a company had twenty-six orange slices to put into containers, how many more slices would they need to fill up the last container?

Answers

Answer:

The last container needs one more slice to be filled up.

Step-by-step explanation:

From the question, we know that only 3 oranges can fit into a container.

However, the company has 26 oranges that need to be inside containers.

We can find out the number of containers that will be filled up completely and the remainder left.

We will do this by dividing the number of orange slices available by the number that can fit into a container.

This is 26 / 3 = 8 remainder 2

Therefore, 8 containers will be filled up, with only two oranges left in the last container.

Remember that each container needs up to 3 oranges to be filled up. Since the last container has only 2 orange slices in it, it needs one more slice to be filled up.

First you have to look at the way the shape is named based on order in each other. ABCD is congruent to GJIH. This means A will be congruent to G, and J will be congruent to B and so on. Same goes with side lengths, so that mean segment GH is congruent to AD based on the order of the name.

So x/3=9
You multiply by 3 on both sides to get x by itself.
So now your answer is x=27
