Polygon ABCD slides 4 units left and 3 units up on the coordinate plane. If the original measure of angle A was 75 degrees, what is the measure of angle A′? (4 points)

75 degrees

100 degrees

105 degrees

180 degrees

The measure of angle A' is equal to the measure of angle A plus 180 degrees. So, the measure of angle A' is 75 + 180 = <<75+180=255>>255 degrees.
