Answer 1

Answer:

........................

Answer 2

AD = x , AB = 2x+1 , AE = x+3 , AC = 2x+8

By, Basic proportionality theorem

AD /AB = AE/AC

x/2x+1. = x+3/ 2x+8

cross multiplication to get

2x^2 + 8x = 2x^2 + 7x + 3

bring everything to left side

2x^2 -2x^2 + 8x -7x -3 =0

x - 3 =0

:. x=3
