The measures of the angles of a triangle are in the extended ratio 2 : 2: 8. What is the measure of the smallest angle?
can someone pretty please show me how to do this?
let the angles be 2x, 2x, and 8x
2x + 2x + 8x = 180
12x = 180
x = 15
so the angles are 30, 30 , and 120°
of course the smallest angle would be 30°
