Triangle ABC is similar to triangle DEF. The sides of ABC are 5,8 and 11. What is the length of the shorttest side of DEF if its perimeter is 60?
Answered by Reiny
Since the sides must be in the same ratio...

let the sides of the new triangle be
5x, 8x, and 11x

5x + 8x + 11x = 80

solve for x, then find 5x

5x + 8x + 11x = 60 , hit the wrong key
