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
1 answer
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.
