D. 81

A. 9

Step-by-step explanation:

This is a right triangle, so the Pythagorean Theorem applies.

Step 1: Define/formula.

The Pythagorean Theorem states that the legs of the triangle, squared, must be greater than the hypotenuse, squared.

The legs of the triangle are the sides that make up the right angle.

The hypotenuse is the longest side in a right triangle.
