Hello!

Use the Pythagorean Theorem to solve for x:
a² + b² = c²
We are given the lengths of two sides, so we can plug those into the formula:
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = x
x = 15.
<span>As you have two fractions, you can cross multiply them. This gives: x/a = y/b to ay = xb. Then divide both sides by b to isolate x: ay/b = x.</span>
