Question 214243This question is from textbook Geometry
: One of two supplementary angles is four times the other. Find the larger Angle.
I set-up:
(180-X)=4(180-x)
and came up with:
X = 180.
I believe my method of
setting it up was correct...
although I do not know where to go from here.

Remember that the two angles together equal 180 degrees
x+4x=180
5x=180
x=36 degrees
4x=144 degrees
