Homework due in 5 minutes

i just wantto know how to find the measure of an angle if the question is like this.

Step-by-step explanation:

what is the question

If I remember correctly, angles 1, 3, 5, 7, 9, and 11 have the same angle of 75 degrees. The other angles should be 105 degrees, because you would take 180 - 75 (the measure of a straight line - the known degree of the angle) to get the other angles. Hope this helps!

Step-by-step explanation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
