Question

Calculate hypotenuse of a right triangle

Answer 1

Basically you need the lengths of the other 2 legs.
By the Pythagorean Theorem, we know that in any right triangle,
hypotenuse^2 = leg1^2 + leg2^2

Answer 2

use Pythagoras theorem (a^2 + b^2 = c^2) :) , c^2 being the hypotenuse (be sure to find square root first tho )
