Use the Triangle Angle Sum Theorem to find the third angle of a triangle if the other two angles measure 25° and 68° . (1 point) Responses 77° 77 degrees 87° 87 degrees 86° 86 degrees 88° 88 degrees

1 answer

To use the Triangle Angle Sum Theorem, we add the measures of the two given angles and subtract the sum from 180 degrees.

25° + 68° = 93°

180° - 93° = 87°

Therefore, the third angle of the triangle measures 87 degrees.
