Answer:

25/3 =x improper fraction

8 1/3 =x mixed number

Explanation:

Using the Triangle Angle Bisector Theorem

AB 10

-------- = -------------

AC 14

x+8 10

-------- = -------------

2x-5 14

Using cross products

10(x+8) = 14(2x-5)

Distributing

10x+80 = 28x-70

Subtract 10x from each side

10x-10x+80 = 28x-10x-70

80 = 18x-70

Add 70 to each side

80+70 = 18x-70+70

150 = 18x

Divide by 18

150/18 =18x/18

25/3 =x

8 1/3 =x
