The perimeter of the triangle shown is 317 inches. Find length of each side.
x inches= inches
5x inches= inches
(8x-5) inches= inches
x + 5x + 8x - 5 = 317 simplify on the left
14x - 5 = 317 add 5 to both sides
14x = 322 divide both sides by 14
x = 23 in
5x = 5(23) = 115 in
8x - 5 = 8(23) - 5 = 179 in
