Question

If the length of the legs of a right triangle are 13 and 13,what is the length of the hypotenuse? Round your answer to the nearest tenth,if necessary.

Answer 1

18.4

Explanation:

13² + 13² = x²

169 + 169 = x²

338 = x²

x = 18.38477....

Answer 2

a² + b² = c²

13² + 13² = c²

169 + 169 = c²

338 = c²

c = √338 or 18.385 or 13√2
