Question

the diagnol of a parellelogram ABCD interest at o if <BOC =85° and <BDC=65°,then find <OAB​

Answer 1

Answer:

20 degree

Step-by-step explanation:

as per the diagram, since angle BDC=OBA=65 degree(alternate angle).

angle BOA=180-85=95 degree(linear pair).

Let angle OAB be x.

so, x+95+65=180

x+160=180

x=180-160

x=20 degree..

hope this helps you my dear friend ❤
