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
