NCERT · Class 7 · Mathematics · The Triangle and its PropertiesIn a triangle ABC, if angle A = 50° and angle B = 70°, find the measure of angle C.
Step-by-Step Solution
Using the angle sum property of a triangle, angle A + angle B + angle C = 180°. Substituting the values: 50° + 70° + angle C = 180° => 120° + angle C = 180° => angle C = 180° - 120° = 60°.
