Question 737623
We are given

The hypotenuse of a right triangle is 4 meters more than the length of the longer leg. The shorter leg is 20 meters. Find the length of the longer leg.

We can use the right triangle formula

(x+4)^2 = x^2 + 20^2

x^2+8x+16 = x^2 + 400

8x = 394  and x = 49.25 meters is the length of the longer leg
