Problema Solution
A lot is in the shape of a right triangle. The shorter leg measures 60 m. The hypotenuse is 20 m longer than the length of the longer leg. How long is the longer leg?
Answer provided by our tutors
Let x be the length of the longer leg.
60^2+x^2=(x+20)^2.
3600+x^2=x^2+40x+400.
40x+400=3600.
40x=3200.
x=3200/40.
=80m.
The longer leg =80m.
