To find the measure of the third exterior angle, we can subtract the sum of the measures of the two known exterior angles from 360 degrees (the total number of degrees in a triangle).
The sum of the measures of the two known exterior angles is 264o, so the third exterior angle would be 360o - 264o = 96o.
Therefore, the measure of the third exterior angle is 96o.
