Question: If two angles of a triangle are 50° and 60°, what is the measure of the third angle?

Options:

  1. 70°
  2. 80°
  3. 90°
  4. 100°

Correct Answer: 80°

Solution: 

The sum of the angles in a triangle is 180°. Therefore, the third angle is 180 - 50 - 60 = 70°.

Questions & Step-by-Step Solutions

If two angles of a triangle are 50° and 60°, what is the measure of the third angle?
  • Step 1: Understand that the sum of all angles in a triangle is always 180°.
  • Step 2: Identify the two given angles, which are 50° and 60°.
  • Step 3: Add the two given angles together: 50° + 60° = 110°.
  • Step 4: Subtract the sum of the two angles from 180° to find the third angle: 180° - 110° = 70°.
  • Step 5: Conclude that the measure of the third angle is 70°.
  • Triangle Angle Sum Theorem – The sum of the interior angles of a triangle is always 180°.
