Find the unknown side length x. Write your answer in simplest radical form. A.35

B.40

C.45

D.48

Please select the best answer from the choices provided

A
B
C
D

So the formula for this type of question is a(square) + b(square)=c(square)
so it would be x+30x30 = 50x50
x+900= 2500
x= 2500-900
x= 1600
since it’s you want to find the length without the root , do square root of 1600 , which is 40
So it’s B

Idon't know what's the answer lol
