129.30

Supplementary angles have a combined sum of 180 degrees. You have one value given, so......

To find the measure of an angle that is supplementary to the given angle, we need to subtract the measure of the given angle from 180 degrees.

In this case, the given angle measures 50.7 degrees.

To find the measure of the supplementary angle, subtract 50.7 from 180:

Supplementary angle = 180 - 50.7
Supplementary angle = 129.3 degrees

Therefore, the measure of the angle that is supplementary to the given angle is 129.3 degrees.

180º - 50.7º = ?
