Find the measure of angle πœƒ.

There’s a few things we should notice here. In this image, there are two angles: angle 50 degrees and angle πœƒ degrees.

These angles share both their initial side and their terminal side. Together, these two angles measure 360 degrees.

To find angle πœƒ, we take 360 degrees, subtract the 50-degree angle, and find that the measure of angle πœƒ is equal to 310 degrees.
