Jed used a protractor to draw an angle measuring 72°. He asked Mark to draw an angle that would be complementary to his angle. What should the measure of Mark's angle be? A.
144°
B.
18°
C.
108°
D.
162°

B

Step-by-step explanation:

Complementary angles are 2 angles that add up to 90 degrees.

If the first angle is 72 degrees, then subtract 90 - 72 to get the measure of the second angle.

90 - 72 = 18

= 18 degrees

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

you probably already have the answer but anyways it's b. 15.0
