What is the length of leg s of the triangle below?

Option C is your answer. 

a² + b² = c²
4² + s² = (√32)²
16 + s² = 32
s² = 16
s = 4

This is an isosceles right triangle as indicated by the 45 degree angles and the right angle. The other side must have the same length since the hypotenuse has to be the longest side in a right triangle.
