    well we know that the sum of the three angles of a triangle add up to 180 degrees right?

    If you work in terms of the first angle, there is 9 x the first angle. There is 180 degrees in a triangle. 180/9=20 degrees. 1st angle = 20 degrees 2nd angle = 2x20=40 degrees 3rd angle = 3x40=120 degrees. added together, you get 180 degress
