NEED HELP PLS Find the value of X. Round to the nearest tenths place

Answer 1

Hello!

$\large\boxed{x = 15}$

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.
