To find the measure of angle C in the given triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the interior angles of a triangle is always 180 degrees.
Looking at the image, we can see that angles A and B are labeled as 60 degrees and 39 degrees, respectively. To find the measure of angle C, we can subtract the sum of angles A and B from 180 degrees:
C = 180 - (60 + 39)
C = 180 - 99
C = 81
Therefore, the measure of angle C is 81 degrees.
use the image to answer the question use the triangle angle some theorem to find the measure of the angle on point C and answer 81 explain why
