Answer:

In ∆ABC angleB=angleC=50°&angleA=80°.

therefore, by given diagram

In quadrilateral OFCE angleC=50° & angleF=angleE=90°.

Hence, by quadrilateral property angle FOE=130°

angleFOE=angleAOB. (since by vertically

opposite angles are

equal)

Hence, angle AOB=130°

this problem is solved by me.
