Problema Solution
One side of triangle is half the longest side. The third side is 8 feet less than the longest side. The perimeter is 72. Find all three sides.
Answer provided by our tutors
let
a = the longest side of the triangle
(1/2)a = other side of the triangle
a - 8 = the third side of the triangle
the perimeter is 72 ft thus
a + (1/2)a + (a - 8) = 72
by solving we find
a = 32 ft

(1/2)*32 = 16 ft
32 - 8 = 24 ft
the sides of the triangle are 32 ft, 16 ft and 24 ft.
