x + (x+6) + (x+30+6)=180
3x+42=180
solve for x (smallest angle), then add 6 and 36 to get the other two.

Let the largest angle be x, so the second angle is (x - 30), and the third angle is (x - 36), so:
x + (x - 30) + (x - 36) = 180, so
x + x - 30 + x - 36 = 180, so
3x - 66 = 180, so
3x = 246, so
x = 246/3, so
x = 82.
so the angles are: 82, 52, and 46.
Hope this helps, Twiggy.

Let the smallest angle be x degrees. Then the next one up is x+6, and the largest one is x+36. So x + x+6 + x+36 = 180. You should be able to solve it from there.

largest angle = x
second largest angle = x-30
third angle = x-36
x+x-30+x-36=180
3x-66 = 180
+66 +66
------ -----
3x = 180
---- -----
3 3
x = 82
substitute x with 82.
largest angle = 82.
second largest angle = 52
third angle = 46

the first angle = 46
the second angle = 52
the third angle = 82
(46+52+82=180)
Good question

a + b + c =180
a =x
b = x-30
c = x-36
x + (x-30) + (x-36) = 180
3x = 246
x = 82
a=82
b=52
c=46

So if the angles are a, b and c
a=b-6
b=c-30
a+b+c=180
Plug, chug and solve
