angle AOC+angle COD+angle DOB= 180° (L.P)
(3x-5)+55+(x+20) = 180
3x-5+x+20 = 180-55
4x+15 = 125
4x = 125-15
4x = 110
x = 110/4
x = 55/2
x= 27.5
(3x-5)+55+(x+20) = 180
3x-5+x+20 = 180-55
4x+15 = 125
4x = 125-15
4x = 110
x = 110/4
x = 55/2
x= 27.5

here is your answer...
hope this helps you...
now put the value of x= 27.5
now angle AOB is 3x-5 that is 77.5
the angle BOD = x+20= 47.5
