Verified by Experts

Let in the quadrilateral two equal angles are $= x^{\circ}$
as we know sum of all angles of a quadrilateral is equal to $360^{\circ}$
so $360^{\circ} = 125^{\circ} + 35^{\circ} + x^{\circ} + x^{\circ}$
$360^{\circ} = 160^{\circ} + 2 x^{\circ}$
$200^{\circ} = 2 x^{\circ}$
$x^{\circ} = 100^{\circ}$
