One leg of a right triangle is 3 millimeters shorter than the longer leg and the hypotenuse is 3 millimeters longer than the short leg. Find the lengths of the sides of the triangle.
You have misstated the problem. The hypotenuse cannot be the same length as the long leg.
No what I put is the exact same thing that is on my home website
@Mertsj is right. That triangle is impossible
Reread your problem. It probably says that the hypotenuse is 3 mm longer than the longer leg.
