You can put this solution on YOUR website! The sum of all angles in any triangle is 180.
A right triangle has one 90 degree angle, and this given triangle also has a 21 degree angle. So you have two angles and one that you need to find.
Therefore you subtract 90 degrees and 21 degrees from 180 and you get 69 degrees.
Therefore the third angle is 69 degrees.
