The Triangle Angle Sum Theorem states that the sum of the three interior angles of a triangle is always 180 degrees.
Given that the angles at points A and B are 60 degrees and 70 degrees respectively, we can find the measure of the angle at point C by subtracting the sum of the angles at points A and B from 180 degrees:
Angle at C = 180 degrees - (60 degrees + 70 degrees)
Angle at C = 180 degrees - 130 degrees
Angle at C = 50 degrees
Therefore, the measure of the angle at point C is 50 degrees.
Use the Triangle Angle Sum Theorem to find the measure of the angle on point C .
