Answer:
110°
Step-by-step explanation:
Two angles in a triangle have measures of 20 degrees and 50 degrees. What is the measure of the third angle?
All the triangle's angles measure adds up to a total of 180º. Always.
So if two of the three angles is 20 and 50 then the third one has to be:
180 - 50 - 20 = 110
