Find the measure of an angle, whose supplement measures eight times its measure

May 13th, 2015

Let the measure of  the angle be x degrees,

the measure of its supplement  will be 180 -x,

therefore, x = (180-x)/8 since 180 - x  is  eight times its measure.

Now you can solve for x:

x = (180-x)/8

8 x =180-x

8x + x = 180

9x = 180

x = 20 degrees

Hope this helps! You can ask any question if you are not satisfied.
