In triangle $ABC$, the measure of $\angle A$ is $86$ degrees. The measure of $\angle B$ is $22$ degrees more than three times the measure of $\angle C$. What is the measure, in degrees, of $\angle C$?

180 degrees in a triangle.

 

180-86 = 94.

 

4 *

 

4C = 72

 

C = 72/4 = 18.

 

ThusC is 18.
