To find the measure of angle C using the Triangle Angle Sum Theorem, we need to know the measures of the other two angles in the triangle. The theorem states that the sum of the angles in a triangle is always 180 degrees.
The formula is: m∠A + m∠B + m∠C = 180°
If we know the measures of angles A and B, we can solve for angle C using this equation.
Assuming angles A and B are provided (for example, let's say m∠A = 50° and m∠B = 70°), we can plug those values into the equation:
50° + 70° + m∠C = 180° 120° + m∠C = 180° m∠C = 180° - 120° m∠C = 60°
If you let me know the measures of the angles A and B, I can provide the exact measure of angle C.
