Q
Q: In triangle ABC, if angle A = 60° and angle B = 70°, what is angle C?
Solution:
Angle C = 180° - (angle A + angle B) = 180° - (60° + 70°) = 50°.
Steps: 5
Show Steps
Step 1: Understand that the sum of the angles in any triangle is always 180°.
Step 2: Identify the given angles: angle A = 60° and angle B = 70°.
Step 3: Add angle A and angle B together: 60° + 70° = 130°.
Step 4: Subtract the sum of angle A and angle B from 180° to find angle C: 180° - 130° = 50°.
Step 5: Conclude that angle C = 50°.
