The measures of the angles of a triangle are in the extended ratio 2: 2: 8. what is the measure of the smallest angle? show work!

The angles of triangle are in the extended ratio 2:2:8.
when it said ratio, put 'x' behind the number they have you.
2x:2x:8x(triangle add up to 180)
so.. 2x +2x +8x =180
12x=180
x=180/12
x=15
now go back to the original question.
plugin 15 to 'x'
2 (15),2 (15),8 (15)
30,30,120
