Answer 2

Angle COB=47 degree

Angle COD=40 degree

Step-by-step explanation:

Angle DOB=87 degree

Angle COA=82 degree

Angle BOA=35 degree

Angle BOA+angle BOC=Angle COA

Substitute the values

$35+\angle BOC=82$

$\angle BOC=82-35$

$\angle BOC=47^{\circ}$

Angle DOB=Angle DOC+angle COB

$87=\angle COD+47$

$\angle COD=87-47$

Angle COD$\angleCOD=40^{\circ}$
