Problema Solution
The equal sides of an isosceles are 5 inches longer than a non equal side. If the perimeter of the triangle is 31 inches find the length of the sides.
Answer provided by our tutors
let
a = the length of the equal sides
b = the length of the non-equal side
the equal sides of an isosceles are 5 inches longer than a non equal side
a = 5 + b
the perimeter of the triangle is 31 inches
2a + b = 31
by solving the system of equations
a = 5 + b
2a + b = 31
we find
a = 12 in
b = 7 in
