In a triangle (the only shape with 3 angles) with the ratios be 2:4:4 you need to split up 180 degrees according to the ratio. you add up all the numbers in the ratio to get 10, then you divide 180/10 to give you 18. Next you multiply 18 by each number in the ratio. When you do this you get the following: 36, 72, 72. these are the angles in degrees
