should i do 9+9+18=180 @mathstudent55

OpenStudy (mathstudent55):

No. Adding to 180 is for angles of a triangle. This is side lengths. For side lengths, take each pair of sides and add their lengths.The sum has to be greater than the third side.

OpenStudy (mathstudent55):

You have two sides of the triangle already given, 18 and 9. Now you have 4 choices for the third side. Any two sides you add must be larger than the third side.
