Question

hey,
answer my question QUICKLY ​

Answer 1

Answer:

8

Step-by-step explanation:

In ΔABC

DE II BC

So, AD/DB = AE/EC

or, 4/(x-4) = x-3/(3x-19)

or 12x - 76 = $x^2$ - 7x + 12

or  $x^2$ - 19x + 88 = 0

Factorizing the quadratic equation, we get-

$x^2$ - 11x - 8x + 88 = 0

or (x-11) (x-8) = 0

So, x= 11 , 8
