Finding the Third Angle of a Triangle

Very Easy Geometry Lines And Angles

In a triangle, the interior angles are determined by the following rules:

If two angles are known, the third angle can be calculated using the formula:

$$ ext{Third Angle} = 180^ ext{o} - ( ext{Angle 1} + ext{Angle 2}) $$

Consider triangle ABC, where angle A measures 50 degrees and angle B measures 60 degrees. What is the measure of angle C?
