In triangle ABC, if angle A = 60 degrees and angle B = 70 degrees, what is the measure of angle C?
Correct Answer: 50 degrees
- Step 1: Understand that the sum of all angles in a triangle is always 180 degrees.
- Step 2: Identify the given angles in triangle ABC. Angle A is 60 degrees and angle B is 70 degrees.
- Step 3: Add the measures of angle A and angle B together: 60 + 70 = 130 degrees.
- Step 4: Subtract the sum of angles A and B from 180 degrees to find angle C: 180 - 130 = 50 degrees.
- Step 5: Conclude that the measure of angle C is 50 degrees.
