Two angles of a triangle have measures with a sum of 84 degrees. what is the measure of the third angle of the triangle?
All of the angles added together MUST equal 180 degrees, so take 180 and subtract 84 from it.
Therefore, the third angle is a 96 degree angle.
Answer: all the angles of a triangle add up to 180 degrees so you take the 180 - 84 which is 96
