Question

Angles A and B are complementary. What is the value of x? 34 56 68 79

Answer 1

Answer: x = 34°

Explanation:

As per definition, complementary angles add up 90°.

In the figure you see angle A measures x + 22° and angle B measures x.

Therefore, according to the definition, you can set this equation:

       

             x + 22° + x = 90°

Solve for x:

• start: x + 22 + x = 90
• combine like terms: 2x + 22 = 90
• subraction property: 2x = 90 - 22
• do the operation: 2x = 68
• division propery: x = 68/2
• do the operation: x = 34

Answer: x = 34°

Answer 2

Answer : The value of x is A ) 34°.
