52° 38° 128 xo degrees​

x = 142°

Step-by-step explanation:

Since angle x and the 38° angle are supplementary angles, we know that the following is true...

x + 38° = 180°

x = 180° - 38°

x = 142°

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.
