Questions & Step-by-Step Solutions

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