Answer:
20
65
95
Explanation:
Remark
You have to use a constant to get the ratio so that it will produce angles that will add up to 180. Let that constant = x
Equation
4x + 13x + 19x = 180
Solution
Add the like terms on the left.
36x = 180
Divide both sides by 36
36x/36 = 180 /36
Combine
x = 5
Answer
4x = 20
13x = 65
19x = 95
Total = 180
