Answer:
75°
Step-by-step explanation:
angle COM & angle MOA are in linear pair , hence the angle COM is 180-120=60.
seg CS is an angle bisector of angle DCB & the angle DCB is right angle=90° , hence angle COM is 45°
The sum of measure of all angles of traingle=180°
hence ,
180°=60°+45°+x
x=180°-105°
x=75°
