Does anyone know how to do this???

Answer 1

Answer:

You need to use Pythagorean's Theorem.

Step-by-step explanation:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

a^2 + b^2 = c^2.
