Use the Triangle Angle Sum Theorem to find the measure of the third angle of the triangle if the measure of two angles are 34.6° and 52.8°.(1 point)
To find the measure of the third angle, add the measures of the two given angles and subtract the sum from 180°.
34.6° + 52.8° = 87.4°
180° - 87.4° = 92.6°
Therefore, the measure of the third angle is 92.6°.
