Step-by-step explanation:

x ≈ 8.57

Step-by-step explanation:

The ray is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

= ( cross- multiply )

8x = 6(20 - x) , distribute

8x = 120 - 6x ( add 6x to both sides )

14x = 120 ( divide both sides by 14 )

x ≈ 8.57 ( to the nearest hundredth )
