The sum of all the internal angles of a triangle is 180. If two of them are each 50, then the third one must be 180 - (2 x 50) = 180 - 100 = 80.
If two angles of a triangle each measure 55 what is the measure of the third angle?
72, 72, 36
180- total of the first two angles= 3rd angle
110180 - (2 x 35) = 110
90 degrees
If two angles of a triangle each measure 55 what is the measure of the third angle?
72, 72, 36

80 degrees
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
96 degrees
The three angles always add to 180, so the third angle would be 40 degrees.
110180 - (2 x 35) = 110
The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees
90 degrees
