If the measure of an angle is 13 degrees, find the measure of its supplement

The supplement would be 167 degrees.

We know this because supplementary angle add up to 180. So we simply subtract the 13 from the original 180.

180 - 13 = 167 degrees

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
