Answer:
A. Acute
Step-by-step explanation:
To start, determine whether you can form a triangle or not. In any triangle, the sum of any two sides must be greater than the third side. In this case, this holds true and we can definitely form a triangle.
Let [tex]c[/tex] be the longest side of the triangle and let [tex]a[/tex] and [tex]b[/tex] be the other two sides.
If [tex]a^2+b^2>c^2[/tex], the triangle is acute.
If [tex]a^2+b^2=c^2[/tex], the triangle is right.
If [tex]a^2+b^2<c^2[/tex], the triangle is obtuse.
Substituting given information:
[tex]7^2+9^2>11^2[/tex], therefore the triangle is acute.

How do i know when to use Sine, Cos or Tan? i struggle so much :c
Answer:
Sin = If you have hypotenuse and the opposite side
[tex]\frac{opp}{hyp}[/tex]
Cos = If you have hypotenuse and an adjacent(close by) side
[tex]\frac{adj}{hyp}[/tex]
Tan = If you have the adjacent and opposite sides
[tex]\frac{opp}{adj}[/tex]
Answer with step-by-step explanation:
Hi there! The Sine, Cosine, and Tangent functions have many different uses and there are various circumstances where you can use them. They are generally used for trigonometry.
Let's start with basic trigonometry for a right triangle. This is likely where these functions were introduced to you.
For any right triangle:
The sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle (o/h).
The cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle (a/h).
The tangent of an angle is equal to its opposite side divided by its adjacent side (o/a).
Any angle's "opposite" side is defined by the side the angle creates or is opposite to the opening of the angle. The adjacent side of an angle is defined by the side that touches/forms the angle that is not the hypotenuse. The hypotenuse is always defined as the longest side of a right triangle.
Oftentimes, students used the phrase "SOH-CAH-TOA" to remember this. The abbreviation simply stands for "Sin-Opposite-Hypotenuse || Cos-Adjacent-Hypotenuse || Tan-Opposite-Adjacent". Regardless of how you remember it, it is crucial to note that this only works for a right triangle.
These are just the basics, but you'll work with sine, cosine, and tangent as you learn about the Unit Circle, Law of Sines, Law of Cosines, sinusoidal functions, the graphs they make, and more.

If base of parellogram is 12 cm lenght is 8cm and prependecular diatance beetween two bases is 7cm find its area and perimeter
Answer:
84 cm^2
10 cm
Step-by-step explanation:
A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length
Area = base x height
12 x 7 = 84 cm^2
Perimeter = 1/2 x ( base + length)
1/2 x (12 + 8) = 10 cm

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the total amount of harvest of bushels be = 9,396 bushels
And , the amount of bushels per acre = 40.5
So , number of acres of land that were harvested is A = amount of harvest of bushels / amount of bushels per acre
On simplifying the equation , we get
The number of acres of land that were harvested is A = 9,396 / 40.5
The number of acres of land that were harvested is A = 232 acres
Hence , the number of acres is 232 acres

Determine whether each function is even, odd, or neither. g(x) = |x-3| neither g(x) = x + x² neither
Answer:
So, both the functions are neither even and nor odd.
Step-by-step explanation:
A function is even if g(x) = g(-x) and odd if g(x) = - g(x).
g(x) = |x-3|
g (-x ) = | -x -3 |
So, the function is neither even and nor odd.
g (x) = x + x²
g (- x) = (- x) + (- x) ² = - x + x²
So, the function is neither even and nor odd.

Determine whether the following sequence is arithmetic or geometric and then
calculate the 8

-25, -15, -5, 5, 10, ...
The sequence is arithmetic / geometric. (Circle one)
8
th term: 10th term:
2-4) Removed
The jump from -25 to -15 is +10
The jump from -15 to -5 is also +10
The jump from -5 to 5 is also +10
Unfortunately, this pattern doesn't hold up. The jump from 5 to 10 is +5
Because the gap isn't the same each time, this tells us the sequence is not arithmetic.
----------------
We can show the sequence isn't geometric either. Pick any term to divide it over its previous term
-15/(-25) = 0.6
-5/(-15) = 0.333 approximate
The result isn't the same, so we don't have a common ratio and that's why this sequence isn't geometric.
----------------
It seems like your teacher made a typo. Please double check with them to make sure that they typed the correct sequence. I have a feeling that 10 should be 15, but I'm not entirely sure.

Answer:
m∠1 = 147°
Step-by-step explanation:
(5x-2)° and ∠1 are supplementary to each other, which means they add up to 180°. However, we don't know the measure of ∠1. So, we need to solve for x to figure out angle (5x-2)°'s measure. Therefore:
(8x+1)°+(5x-2)°+90°=180°
8x+1+5x-2+90=180
13x+89=180
13x=91
x=7
This means the measure of angle (5x-2)° is 33°, making the measure of ∠1 equal to 147°.

What is Pythagoras theorem?The Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Given is a square, with diagonal of 6 units we need to find the measure of the sides, of the square,
By the definition of the Pythagoras theorem,
s² + s² = 6²
2s² = 36
s² = 18
s = 3√2
Therefore, we get s = 3√2
Hence, the measure of the sides, of the square, is 3√2 units

Race car driver traveled at an average speed of 120 miles per hour to finish a race in 2 hours. What is the length of the race?
Answer:
240
Step-by-step explanation:
If you are going 120 mph for 2 hours. You simply multiply the two values, giving 240 and the units for this is miles because in the multiplication, the units are m/h * h and this cancels out the hours and leaves just miles.
Answer:
240miles

Find the sixth term of the geometric sequence 9, -27, 81,
a6
Answer:
The sixth term of the sequence = -234
Step-by-step explanation:
The formula of a geometric sequence is:
aₙ = a₁ + r⁽ⁿ⁻¹⁾
Where;
aₙ = the term value
n = the term that has to be found out
a₁ = first term in the sequence
r = common ration
Here in this situation:
aₙ = unknown
n = 6
a₁ = 9
r = -3
Therefore the solution would be:
a₆ = 9 + (-3)⁶⁻¹
a₆ = 9 + (-3)⁵
a₆ = 9 + (-243)
a₆ = -234
Therefore the sixth term of the sequence would be: -234
Hope this helps!
