What’s the value of X ???

Step-by-step explanation:

So since triangle jkl and wyz are similar angles j and w must equal each other, angles k and y must equal each other, and angles l and z are equal. So to find x just set 4x-13 equal to 71

4x-13=71

add 13 to both sides to cancel the -13 from the left

4x=84

and divide both sides by 4 to cancel the 4 on the left

x=21
