Question

Helppppppppp mathhhhhhhhhhhh

Answer 1

Since this is an isosceles right triangle the sides have equal length.  From the Pythagorean Theorem:

h^2=x^2+y^2, where h=hypotenuse, x and y are the side lengths.

Since x=y=s and we are told that h=22 we can say:

2s^2=22^2

2s^2=484

s^2=242

s=√242

s=√(121*2)

s=√(11*11*2)

s=11√2
