2 line segments intersect to form an angle that has a measure of 50.7 degrees. What is the measure in degrees of an angle that is supplementary to this angle?
180 - 50.7 = ?
Wait... So you can answer everything but a simple question? You should be able to figure this out! C'mon.. Grab a paper. Put it like this
180

50.7

To find the measure of an angle that is supplementary to another angle, you have to subtract the measure of the given angle from 180 degrees.
In this case, the given angle measures 50.7 degrees. Therefore, the supplementary angle can be calculated as follows:
Supplementary angle = 180 degrees - Measure of given angle
Supplementary angle = 180 degrees - 50.7 degrees
Supplementary angle = 129.3 degrees
So, the measure of the angle that is supplementary to an angle measuring 50.7 degrees is 129.3 degrees.
