Question 230014
A lot is in the shape of a right triangle. The shorter leg measures 60 meters. The hypotenuse is 20 meters longer than the length of the longer leg. How long is the longer leg?
---------
a^2 + b^2 = c^2
60^2 + b^2 = (b+20)^2
3600 + b^2 = b^2 + 40b + 400
3600 = 40b + 400
40b = 3200
b = 80 meters
