Answer:
x=75
Step-by-step 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

1. The radical expression
![\sqrt[n]{}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%7D%20)
with even n requires <span>a variable with positive quantity. For example, if you have
![\sqrt[4]{x^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7Bx%5E3%7D%20)
, then always
![x^3\ge 0](https://tex.z-dn.net/?f=x%5E3%5Cge%200)
.

2. If you have radical expression
![\sqrt[n]{}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%7D%20)
with odd n, ia variable may be arbitrary. For example, for
![\sqrt[7]{x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B7%5D%7Bx%7D%20)
you can consider all real x.

Well x stands for an unknown number. So lets say the value of x is 11 you would do 11=9 3x 11 and then multiply 33 x 2
