`8x - 10 + 4x + 52 = 90 \\ 8x + 4x - 10 + 52 = 90 \\ 12x + 42 = 90 \\ 12x = 90 - 42 \\ 12x = 48 \\ x = (48)/(12) \\ x = 4`

➳The value of x = 4.

Now, the value of the angles,

`8x - 10 \\ = 8(4) - 10 \\ = 32 - 10 \\ = 22`

➳ 1 angle = 22°

`4x + 52 \\ = 4(4) + 52 \\ = 16 + 52 \\ = 68`

➳ 2 angle = 68°
