+208 The perimeter of a triangle is 42 feet. One side of the triangle is one foot longer than the second side. The third side is five feet longer than the second side. Find the lengths of all three sides (in feet). (Enter your answers as a comma-separated list.)
+36915 x = short side
x + 1 = second side
(x+1) + 5 = third side all three sides added together = 42 solve for x = short side
Then x+ 1 = second side
then (x+1) + 5 = third side
