Find the exact length of the third side.
5
3

Hi there! :)

Use Pythagorean theorem to solve:

a² + b² = c² where "c" is the hypotenuse or the diagonal:

Plug in the given values:

(3)² + b² = (5)²

9 + b² = 25

Subtract 9 from both sides:

b² = 16

Take the square root of both side:

√b² = √16

b = 4.
