Polygon ABCD slides 4 units left and 3 units up on the coordinate plane. If the original measure of angel a was 75 degrees what is the measure of angle a' 75 degrees

100 degrees

105 degrees

180 degrees

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

b. x- 48 =120

step-by-step explanation:
