Angles A and B are complementary.

What is the value of x?

34

56

68

79

Angle A = x + 22°.

Angle B = x.

And since the angles are complementary:

A + B = 90°

x + 22° + x = 90°

2 x + 22° = 90°

2 x = 90° - 22°

2 x = 68°

x = 68° : 2

x = 34°

Angle A = 56°, angle B = 34°

Answer : The value of x is A) 34°.
