Question

Find the length of the third side. If necessary, round to the nearest tenth.
15
20

Answer 1

Answer: The third side has a length of 25 units.

Step-by-step explanation:

In a right triangle, we can use $a^2+b^2=c^2$ to find the side length of c.

$15^2+20^2=c^2$

225 + 400 = 625

$\sqrt 625$ = 25

Therefore, c = 25.
