The length of a hypotenuse of a right triangle is 2 metre more than the longer leg. The length of the longer leg is 7 metre more than the length of the shorter leg. Find the number of metre in length of each side of the right triangle.

Hi Ali.

Use the Pythagorean Theorem. Let x = the length of the long leg.

Then (x+2)^{2} = x^{2} + (x-7)^{2}.

Solve for x.
