Angle 1 . . . . . 14 parts
Angle 2 . . . . . 5 parts
Angle 3 . . . . . 11 parts
Total . . . . . . . . 30 parts
But the total of the angles in ANY triangle is always 180 degrees.
SO ... 180 degrees / 30 parts = 6 degrees per part.
Angle 1 . . . . . 14 parts x (6° / part) = 84°
Angle 2 . . . . . . 5 parts x (6° / part) = 30°
Angle 3 . . . . . 11 parts x (6° / part) = 66°
Check: Total . . . . . . . . . . . . . . . . . . 180° yay !
