a) 100 degree
b) 45 degree
c) 90 degree
d) 180 degree

Please give full process and don’t write answer if don’t know.

Answer 1

Answer:

I believe, answer is 90° but I am not sure

Step-by-step explanation:

if angle PMS = 90°, by linear pair we can say that angle RMS = 90°

then angle MSR or Y = 45°

Y = X (alternate interior angles)

ATQ

X+Y=45+45=90°
