☜☆☞hey friend!!! ☜☆☞

where is your figure...
but no problem I understand your problems

here is your answer ☞

________-

AB and CD intersect at O and CD is a straight line.

(i) ∠COA+ ∠AOD = 180°   (linear pair)

42°+ ∠AOD  = 180°

∠AOD  = 138°_____answer

(ii) ∠COA and ∠BOD are vertically opposite angles. 

∴∠COA = ∠BOD = 42°   [from (i)]

(iii) ∠COB and ∠AOD are vertically opposite angles.

∴∠COB = ∠AOD = 138°  [from (i)]

I think my answer is capable to clear your confusion..
