Which equation can be used to find x the length of the hypotenuse of the right triangle?

For any right triangle, the longest side is called the hypotenuse. Therefore, by Pythagorean theorem it is true that:

Where:

x: Hypotenuse

a, b: The other two sides.

For instance, if we have a right triangle whose sides measure:

Then, the hypotenuse can be found as:

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
