Question

Hi can you please guide me through the steps to solve this problem? ​

Answer 1

`x = 27 (1)/(3)`

Explanation:

The little square on ∠AOC indicates that it is a right angle, which means that ∠AOC= 90°

∠AOC= ∠AOB +∠BOC

90°= (x+8)° +2x°

x +8 +2x= 90

3x +8= 90 (simplify)

3x= 90 -8 (-8 on both sides)

3x= 82

x= 82 ÷3

`x = 27 (1)/(3)`
