An unusual triangle wall flag at the United Nations has a perimeter of 255 millimeters. The second side is 18 millimeters longer than the first side. The third side is 3 millimeters shorter than the first side. Find the length of each side.
Answer provided by our tutors
The three sides are x,(x+18), (x-3)

x+x+18+x-3=255
x = 80
So the three sides are 80 mm, 98mm, 77mm
