angle aob = 90 degree and CD is a straight line angle Coe = 105 degree angle Bod = 2x degree angle Doe = 3X degree and Angle AOC = Y find X and Y

Dear Student, 
<DOE + <COE =180°  ( Linear pair)
105°+3x=180
3x= 75°
x=25°
<DOB =2x =50°

Now,
<AOC+<AOB+<DOB =180°  (Linear pair)
y+90°+50°=180°
y= 40°


Regards
