The hypotenuse of a right triangle is 34 units long, and one leg is 14 units longer than the other. What is the length of the shorter leg?

Answer and explanation

Correct answer: 16

Let the shorter leg be \(x\) units. Then the longer leg is \(x+14\) units. By the Pythagorean theorem, \(x^2+(x+14)^2=34^2\), which simplifies to \(x^2+14x-480=0\). Factoring gives \((x-16)(x+30)=0\), so \(x=16\) or \(x=-30\). Since a length cannot be negative, the shorter leg is 16 units. Remember that 30 units is the longer leg, not the shorter one.
