Question

plz answer as fast as possible.​

Answer 1

Answer:

Extend OD to cut ab in suppose z

Step-by-step explanation:

87 degrees

Answer 2

Step-by-step explanation:

join OA,OC

Angle BAO=38(AB||CD Interior alternate angles)

IN Triangle AOB

Angle OAB+Angle AOB+Angle OBA=180(Angle sum property)

38+Angle AOB+55=180

Angle AOB=180-(38+55)

Angle AOB =87

Angle AOB+Angle DOB=180(Angles on the stright line)

87+Angle DOB=180

Angle DOB=180-87

Angle DOB=93

so the value of x=93
