Question

What is the value of x?

Answer 1

X=75

Explanation:

FD/DJ=SJ/YJ=FS/DY(BEING CORESSPONDING SIDE OF SIMILAR TRAINGLES)

TAKING FIRST AND SECOND RATIO

OR X/50=63/42

OR X*42=63*50

OR X=3150/42

OR X=75

Answer 2

x=75

Explanation:

∆FSJ~∆DYJ

so the sides are proportional

SJ/YJ=FJ/DJ

(63+42)/42=(x+50)/50

105/42 ×50=x+50

125-50=x

x=75
