Question: In triangle ABC, if angle A = 50° and angle B = 60°, what is the measure of angle C?

Options:

Correct Answer: 70°

Solution:

The sum of angles in a triangle is 180°. Therefore, angle C = 180° - (50° + 60°) = 70°.

In triangle ABC, if angle A = 50° and angle B = 60°, what is the measure of angle C?

In triangle ABC, if angle A = 50° and angle B = 60°, what is the measure of angle C?

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 50 degrees and angle B is 60 degrees.
Step 3: Add the measures of angle A and angle B together: 50 degrees + 60 degrees = 110 degrees.
Step 4: Subtract the sum of angles A and B from 180 degrees to find angle C: 180 degrees - 110 degrees = 70 degrees.
Step 5: Conclude that the measure of angle C is 70 degrees.

Triangle Angle Sum Theorem – The sum of the interior angles of a triangle is always 180°.
