Two angles in a triangle have measures of 42° and 82°.
What is the measure of the third angle?
OA. 56°
B. 40°
C. 124°
D. 166°

Answer 1

The measure of the third angle is 56°.

Step-by-step explanation:

The measure of the third angle in a triangle can be found by subtracting the sum of the measure of the two given angles from 180°. In this case, the measure of the third angle is 180° - (42° + 82°) = 56°.
