The perimeter of a triangle is 57in. The longest side is 13in. longer than the medium side, and the medium side is 7 in. more than the shortest side. find the length of each side of the triangle.

Question

The length of the longest side is ___in, the length of the medium side is __in. and the length of the shortest side ___in.

Answer 1

well, just use what you're told. If the medium side is x, then

x-7 + x + x+13 = 57

Now just find x and you're almost done.

Answer 2

x=17
x-7=10+17=27+17=44+13=57
