Problema Solution
john walks on a path forming a right triangle,whose hypotense is 39m.One leg is 21m longer than the other.
Answer provided by our tutors
let
c = 39 m the hypotenuse
a and a + 21, are the legs and a>0
using the Pythagorean Theorem we have:
a^2 + (a + 21)^2 = c^2
a^2 + (a + 21)^2 = 39^2
by solving we find:
a = 15 m
click here to see the step by step solution of the equation:
a + 21 = 15 + 21 = 36 m
the legs are 15 m and 36 m.
