Question

What is the value of x?
A.34
B.56
C.68
D.79

Answer 1

A complementary angle is two angles whose sum add up to 90°

Explanation:

To find x you have to add both angles.

x + 22° + x° = 90°

(x + x) + 22 = 90

Combine like terms.

2x + 22 = 90

Subtract 22 from both sides

2x = 68

Divide both sides by 2

x = 34

The value of x is 34°
