Answer:
Side c has a length of √145, or approximately 12.04.
Step-by-step explanation:
Because this is a right triangle, you can use the Pythagorean theorem to solve it. In a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse. Or in this example:
c² = 9² + 8²
So we can solve it:
c² = 9² + 8²
c² = 81 + 64
c² = 145
c = √145
c ≈ 12.04
