Explain how to find the measurement of the angle shown on the protractor. What is the measurement of the angle?

• Find the sum of 155° and 45°. The angle measures 200°.

• Find the difference between 155°and 45°. The angle measures 110°.

• Use the smaller measurement because the angle is acute. The angle measures 45°

• Use the larger measurement because the angle is obtuse. The angle measures 155°.
