Question

Angles AandB are complimentary. Angle A measures x. Angle B measures (2 x +9) what is the value of x

Answer 1

Answer:

x = 27°

Step-by-step explanation:

Hello!

Complementary angles add up to 90°.

Since angles A and B are complementary, we can sum up the equations to 90° and solve for x.

Solve for x

• $A + B = 90\°$
• $x + 2x + 9\° = 90\°$
• $3x + 9\° = 90\°$
• $3x = 81\°$
• $x = 27\°$

The value of x is 27°.
