*The lengths of two sides of ABC are 15 and 20, and the triangle perimeter is 50. What is the third side of ABC?*

The perimeter of a triangle is the sum of the lengths of all three sides.

You know the length of two sides; namely 15 and 20. These two sides total 35.

So the third side has to be 50 (the total perimeter) minus the other two sides.

50 – 35 = **15 the length of the third side**
