In the question you will do

35 is the biggest side it’s named by hypotenuse

So you will do 35=21 to the power x +x

So after you do it it will be

X=441 -35 it will be 406 and after you finish you will do it in the calculator so

The Answer is : 20.15
Theres an easier way. Pythagorean theorem-
A^2+B^2=C^2
A and B are legs while C is the hypotenuse or slanted one.
So rearrange formula.
C^2 - A^2=B^2
1225 - 441 = B^2
784= B^2
Square root it now
28=B
