<PRE><B>Question 200897</B>
One side of a triangle is half the longest side. The third side is 10 meters less than the longest side. Ther perimeter is 45 meters. Find all three sides.
---------------------
2x = longest side
x = 2nd side
2x-10 = 3rd side
Add them up.
2x + x + 2x-10 = 45
5x-10 = 45
5x = 55
x = 11  (2nd side)
2x = 22 (longest side)
2x-10 = 12 (3rd side)
