Answer:
72°
Step-by-step explanation:
Start by putting the information you’re given into an equation. The angle measure is 4 times the compliment so it has the measure 4x.
Complementary angles are two angels with a sum of 90°.
So our equation will be 4x + x = 90
Add your like terms to get 5x = 90
Divide 90 by 5 to get x by itself.
X = 18
Since the angle we’re trying to find is 4 times the compliment you’re going to multiply 18 by 4 which will give you your answer of 72°
