Question

The measurements of two sides of a triangle are 12 inches and 15 inches. Which length could be the measurement of the third side of the triangle?

Answer 1

Answer: 9

Step-by-step explanation:

If we assume a right triangle with a hypotenuse of 15 and a leg of 12, we can use the Pythagorean theorem to find the other leg, which is 9. (also, knowing your Pythagorean triplets could help save some time).
