hii friend

here's your answer looking for

from the given figure,

in triangle AOB,

angle OAB= angle OBA. (opp. angles of iso. triangle)__________(1)

angle AOB + angle OAB + angle OBA = 180

angle AOB +35+35=180

angle AOB=180-70

angle AOB=110

so,. angle DOA + angle AOB = 180. ( linear pair).

angle DOA +110=180

angle DOA = 180-110

angle DOA=70
