I will do the first, and start you off on the second
smallest angle -- x
medium-sized angle -- 3x
larges angle --- 6x
x + 3x + 6x = 180
10x = 180
x = 18
3x = 54
6x = 108 , not 108+54+18 = 180
medium sized angle = x
small angle = (1/3)x
large angle = 2x
x + (1/3)x + 2x = 180
multiply by 3
3x + x + 6x = 540
10x = 540
x = 54
(1/3)x = 18
2x = 108 , notice we got the same answers
you do the 3rd way.
Reiny...yes, thank you. I appreciate the help so much. I did have the some work-up for X=smallest angle. Thanks for starting me out for the next 2 angles.
