Firstly you have to find the value for OCD and ODC. Both are 54° (since they are isosceles).

Every straight lines = 180° in total.

Then find values for triangle AOD and BOC. Note that the interiour angles are defined by :-

(n-2) × 180° where n is the number of edges.

Triangle AOB is sadly not isosceles though.

Thank you brother

My approach for this question uses an upper secondary maths method. I have long thought about the geometrical aspects of the diagram and tried all avenues to approach it the easier way, but could not find one in time.
