Question 635012
if two angles are supplementary and one angle is 11 times as big as the 
other angle, find the measure of the larger angle.
:
Let x = one angle
then
11x = the larger angle
:
Supplementary, means the two angles add up to 180
x + 11x = 180
12x = 180
x = 180/12 
x = 15 degrees is the small angle
11(15) = 165 degrees is the larger angle
