Two angels of a triangle measure 65 and 75. Which is not the measure of an exterior angle of the triangle

An exterior angle is the sum of the two other interior angles

the three interior angles are 55 and 65 and 180 - (55+65) = 60

so 60 + 55 = 115

60 + 65 = 125

65 + 55 = 120

brainlest answer.
