Question 72696: The base of an isosceles triangle is 12 in. less than the length of the equal sides. If the perimeter of the triangle is 39 in., find the length of each of the sides. Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! B=L-12
L-12+L=L=39
3L=39+12
3L=51
L=51/3
L=17 IN. IS THE LENGTH OF THE SIDES.
BASE=17-5
BASE=12
PROOF
5+17+17=39
39=39
