All angles of a triangle should add up to be 180.
So 180 - 40 - 40 = 100
So angle c = 100

Every triangle has a sum of 180 degrees. We are given two of them, so we add 40 and 40 to get the sum of 80. Since we know this, we can subtract 180 and 80 to get the last angle measurement. 180-80 is 100, so Angle C would be 100 degrees.
