Answer 1

17?

Explanation:

a squared + b squared = c squared (hypothenuse longest side)

square them, then add them and square root them.

Answer 2

17

Explanation:

We can find the longest side I.e. Hypotenuse using pythogorean theorem.

`{8}^(2) + {15}^(2) = {x}^(2) \\ 64 + 225 = {x}^(2) \\ 289 = {x}^(2) \\ x = √(289) \\ x = 17`

This is your answer hope it helps :)
