Consider △AOB
we get
AO=OB
We know that the base angles are equal
∠OAB=∠OBA=35
o
By using the sum property of the triangle
∠AOB+∠OAB+∠OBA=180
o
By substituting the values we get
∠AOB+35
o
+35
o
=180
o
∠AOB=180
o
−70
o
∠AOB=110
o
from the figure, we know that the vertically opposite angles are equal
⇒∠DOC=∠AOB=y=110
o
In △ABC
We know that ∠ABC=90
o
Consider △OBC
We know that
∠OBC=x
o
=∠ABC−∠OBA
By substituting the values
∠OBC=90
o
−35
o
∠OBC=55
o
therefore x=55
o
, y=110
o
