Can anyone please explain to me how to get the missing answers? Thanks.

I found out ABC, but I can't figure out OAD.
value of angles RCB =56 ABC=70.5 OAD=OAC + DCT CAD =DCT Triangle OAC is isosceles.Finish it after finding angleAOC
How is ABC 70.5?

And? Opposite angles add up to 180 is the theory. Therefor ABC is 39. Why would it be one half of 141? And I checked, my answers were right.
if angle ADC =141 arc ADC =78,angle AOC =78 not obtuse as you show. I assumed that arc ADC =141
What arc?
Still in need of an answer.
angleOAD = 74 deg Ichanged your drawimg moving A closer to C making angle AOC acute
