Natasha is measuring the angles of a triangle. She measures the first two angles and gets 60 degrees and 80 degrees. What should be the measure of the third angle?
A) 10 degrees
B) 20degrees
C) 40 degrees
D) 220 degrees
The total measure of a triangle is 180 degrees, therefore to find the other angle you would need to add the first two, and then subtract that sum from 180.
