Best Answer

In order to have a hypotenuse, the triangle must be a right triangle - in this case we have an isosceles right triangle. Using the Pythagorean theorem:

a2 + b2 = c2

152 + 152 = c2

225 + 225 = c2

450 = c2

c = √450

c = √2*9*25

c = 15√2

15 units in length

I assume you mean a right triangle. Use the Pythagorean theorem.a2 + b2 = c2c2 = 152 + 82c = sqrt(152 + 82)c(hypotenuse) = 17==============
