FInd x (Will mark brainliest)

Step-by-step explanation:

(2x-4)(20-8) = 15×8

(2x-4)(12)= 120

2x-4 = 120/12

2x-4 = 10

2x = 10+4

2x= 14

x = 14/2

x=7

9514 1404 393

  x = 7

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  (2x -4)/8 = 15/(20 -8)

  3(2x -4) = 2(15) . . . . . . . . multiply by 24

  2x -4 = 10 . . . . . . . . . divide by 3

  x -2 = 5 . . . . . . . . divide by 2

  x = 7 . . . . . . . add 2
