A triangle has two angles measuring 40° and 65° . Use the Triangle Angle Sum Theorem to find the measure of the third angle.(1 point) °
The Triangle Angle Sum Theorem states that the sum of the three interior angles of a triangle is always equal to 180°.
So, to find the measure of the third angle, we can add the measures of the two given angles and subtract the result from 180°:
40° + 65° = 105°
180° - 105° = 75°
Therefore, the measure of the third angle is 75°.
