Question

Two angles are complementary. One angle measures (5x)degrees and the 30degrees which equation will help to solve for the value of x

A.5x=30
B.5x+30=90
C.5x-30=90
D.5x+30=180

Answer 1

B. 5x+30 =90

Explanation:

complementary angles are a sum of 90

so to find x you need to add up the two angles

Answer 2

5x+ 30 = 90

Explanation:

Complementary angles add to 90 degrees

Add the angles together and set equal to 90

5x+ 30 = 90
