Answer:

x = 85

Explanation:

Because this is a right triangle, we can use the Pythagorean Theorem:

a² + b² = c²

Where c is the hypotenuse, or the longest side. This is opposite to the right angle of the right triangle. So now you have:

84² + 13² = x²

7056 + 169 = x²

7225 = x²

√7225 = √x²

85 = x

x = 85
