The sum of the measures of all exterior angles of any triangle is always 360 degrees. Therefore, the sum of the measures of two exterior angles of a triangle is 360 - 264 = <<360-264=96>>96 degrees.
Since the third exterior angle is the only angle left, it must have a measure of 96 degrees.
the sum of the measures of two exterior angles of a triangle is 264 degrees. What is the measure of the third exterior angle?
