Question 432967: The sum of two angles of a triangle is 150 degrees. What is the supplement of the third angle of the triangle?
The first two cannot be 90 degrees, so I thought it would be 75 and 75 and the third angle 30. Thus according to the answer key it is 150. I do not understand why it is 150 degrees. Would you explain it to me? Thanks.

If the third angle is 30, then the supplement of thirty is 150 (supplement means they add up to 180)
