Answer:

B.) 73°

Step-by-step explanation:

To find m<A, first you must find it's supplementary angle. In order to do this, you must determine the missing interior angle. We'll call the missing angle x

A pentagon has 540°. Add up the known angles.

96°+118°+115°+104°+x = 540°

433°+x = 540°

x = 107°

Now that we know the value of x, we can find the m<A. Supplementary angles are two angles that add up to 180°, which is a flat line. We can see in the diagram that m<a + 107° is a flat line, meaning m<a + 107° = 180°

Solve accordingly.

m<a + 107° = 180°

m<a = 73°

Find the distance between two points -9,-5 and 0,7

Arada [10]

To find the distance, you need to subtract the second point from the first one. So:

0 - (-9) = 9 ( two minuses turn into a positive)

And

7 - (-5) = 12

So the difference between the points is 9 units on the x- axis and 12 on the y-axis.

Hope this helped and pls mark as brainliest!

Answer:

Step-by-step explanation:

Hint: 1- 2sin²x = Cos 2x

LHS = 1 - 2Sin² (π/4 - Ф/2)

= Cos 2 *(π/4 - Ф/2)

= Cos 2*π/4 - 2*Ф/2

= Cos π/2 - Ф
