8) The angles of an octagon are 135 degrees and since they're divided in the middle the angle measures are 67.5.
So 180-67.5-67.5=45 so the measure of the inner degree of each small triangle is 45. There are 3 triangles between points T and P (going clockwise) so its 45(3) is 135 degrees. Your answer is 135 degrees
9) There are 5 triangles between U and I (going counterclockwise) so its 45(5) which is 225
