The Triangle Angle Sum Theorem states that the sum of the angles in a triangle is 180 degrees.

Let x be the measure of the third angle.

Since we have two known angles of 40° and 65°, we can find the measure of the third angle by subtracting the sum of these two angles from 180°:

x = 180° - (40° + 65°)

x = 180° - 105°

x = 75°

Therefore, the measure of the third angle is 75°.
