1.      Sabrina was repairing the post on her mailbox. She wanted the post to be perpendicular to the ground, but her protractor showed that the post was at a 88-degree angle with the ground. She incorrectly concluded that she needed to increase the angle by 22 degrees. What should Sabrina have concluded?

• The angle needs to be increased by 2 degrees to get a 90-degree angle.

• The angle needs to be decreased by 22 degrees to get a 90-degree angle

• The angle needs to be decreased by 33 degrees to get a 45-degree angle

• The angle needs to be increased by 102 degrees to get a 180-degree angle.
