Question 804849: Angles A and B are supplementary. The ratio of the measure of angle A to angle B is 3:9. Find the measure of the larger angle.
Answer by erica65404(394) (Show Source): You can put this solution on YOUR website!
supplementary angles add up to 180.
The ratio is 3:9.
The ratio points are 12.
take 180 and divide it by 12 to figure out hoe many degrees are in 1 ratio point.
180/12=15
now multiply the ratio by 15
45:135
The larger angle is 135
