Step 1: Recall the principle of the right angle triangle

NOTE: You know that one of the angles measures exactly 90°.

Step 2: Apply the principles and add up the measurements of the sides you know

EXAMPLE: 41° + 90° = 131°

Step 3: Subtract that number from 180°.

EXAMPLE: 180° - 131° = 69°.

The measurement of that third angle is 49°.
