Question

from adjacent figure DE is parallel to BC then find the value of x
​

Answer 1

Answer:

x=1/8

Step-by-step explanation:

Because, DE is parallel to BC,

AD/AB=AE/AC

(x+4)/(x+10)=(3x+1)/(3x+3)

(x+4)(3x+3) = (3x+1)(x+10) by cross multiplication

3$x^{2}$+15x+12=3$x^{2}$ + 31x+10

31x-15x=12-10

16x=2

x=2/16=1/8
