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.
Use the Pythagorean Theorem. Let x = the length of the long leg.
Then (x+2)2 = x2 + (x-7)2.
Solve for x.
