The shorter leg of a right triangle is 20 yards. If the hypotenuse is 29 yards, how long is the other leg?

Step 1. Use the Pythagorean Theorem which states that the sum of the squares of the legs (given legs a and) is equal to the square of the hypotenuse c.

Step 2. Let a=20 and c=29, we can find the other leg b as follows

Subtract from both sides of the equation

Take the square root of b to both sides of the equation

Step 3. ANSWER. The length of the other leg is 21 yards.

I hope the above steps were helpful.
