Question

Angles A and B are complementary to each other. If m2A = 26° + x and

m2B - 38° + X, what is the value of x?
A.) 13
B.) 14
C.) 58
D.) 18

Answer 1

13

Explanation:

Complementary angles add to 90 degrees

A+ B = 90

26+x + 38+x = 90

Combine like terms

2x+64=90

2x+64-64 = 90-64

2x = 26

Divide by 2

2x/2 = 26/2

x = 13
