Answer:

The value of x is 20°.

Step-by-step explanation:

AOB = ABO = 3x + 10° (Angles opposite to equal sides; given that AB=AO)

AOB = DOC = 3x + 10° (Opposite angles at intersecting lines)

ODC = DOC = 3x + 10° (Angles opposite to equal sides; given that CO=CD)

OCD + DOC + ODC = 180° (Angle sum of a triangle)

=> 2x + 3x + 10° + 3x + 10° = 180°

=> 8x + 20° = 180°

=> x = (180°-20°)/8

=> x = 20°
