Question 844875: Two angles are supplementary. One angle measures 15 degrees more than 4 times the other.
What is the measure of the larger angle in degrees?

You can put this solution on YOUR website!
If two angles are supplementary they equal
to 180 degrees when added.
Small angle = x degrees
Large angle = 15 + 4x degrees.
x + (15 + 4x) = 180
x + 15 + 4x = 180
5x + 15 = 180
5x = 180 - 15
5x = 165 degrees
x = 33 degrees.
Small angle = 33 degrees
Larger angle = 147 degrees.
Hope this helps.
