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 angles in a triangle is always 180 degrees.
Therefore, we can find the measure of the third angle by subtracting the sum of the given angles from 180 degrees.
40° + 65° = 105°
180° - 105° = 75°
Therefore, the measure of the third angle is 75°.
