Question

I need help in geometry urgently!!!

Answer 1

x = 6

Explanation:

According to Exterior Angle Property of a triangle , measure of an exterior angle is the sum of its opposite interior angles.

Using the exterior angle property ,

`17x - 23 = 3x + 17 + 8x - 4`

`= > 17x - 23 = 11x + 13`

`= > 17x - 13x = 23 + 13`

`= > 6x = 36`

`= > x = (36)/(6) = 6`
