You can put this solution on YOUR website!

recall: Supplementary angles add up to 180 degrees.
if an angle is x, its supplement is 180-x
and if an angle is 30 degree more than twice the measure of the supplement, then
x=2%28180-x%29%2B30
x=360-2x%2B30
x%2B2x=390
3x=390
x=390%2F3
highlight%28x=130%29
so, your angle is 130 degrees and its supplement is 50 degrees.
