Question

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

Answer 1

x = 27°

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°.
