The hypotenuse of a right triangle is twice as long as one of its legs. The other leg is nine inches long. Find the hypotenuse.

You can put this solution on YOUR website!

You MUST understand the Pythagorean Theorem formula. c is for hypotenuse, b and a are the legs. Analyze the description and assign variables like THIS:

a,b,c;
c=2a, and b=9.

Use the formula!

highlight_green%28a%5E2%2B9%5E2=%282a%29%5E2%29

Solve for a;
use a to evaluate c.
