If you want to find the possibilities for the third side, add the numbers together:15+18=33. Then subtract the numbers 18-15=3. The third side must be between these two numbers but not including these numbers. Therefore the only number that does not fit into this range is 36. Remember that the third side could NOT be 3 or 33.

The sum of any two sides must be greater than the third side.
15+18=33
so the third side must be less than 33 which excludes d 36
