In the figure, $$\angle BDC=$$

$$ABCD$$ is a cyclic quadrilateral $$AE$$ is drawn parallel to $$CD$$ and $$BA$$ is produced. If $$\displaystyle \angle ABC=92^{\circ}$$ and $$\displaystyle \angle FAE=20^{\circ},$$ then $$\displaystyle \angle BCD=$$ 

In the given figure, if $$O$$ is centre, then external $$\angle AOC=$$

In the given figure, $$\angle DBC=22^{\circ}\;and\;\angle DCB=78^{\circ}$$ then $$\angle BAC$$ is equal to:

In the given figure, $$CDEF$$ is a cyclic quadrilateral, $$DE\;$$and$$\;CF$$ are produced to $$A\;$$and$$\;B$$ respectively such that $$AB\;\parallel\;CD$$. If $$\angle FED=80^{\circ}$$, find $$\angle FBA$$.

$$PQ$$ is a diameter and $$PQRS$$ is a cyclic quadrilateral. If $$\angle PSR=150^o$$, then measure of $$\angle RPQ$$ is:

In figure, $$O$$ is centre, then $$\angle BXD=$$

$$ABCD$$ is a cyclic quadrilateral inscribed in a circle with the centre $$O$$. Then $$\angle OAD$$ is equal to:

$$ABCD$$ is a cyclic quadrilateral. Then, find $$\angle x^{\circ}$$ as given in the figure.

In the given figure, the value of $$'a'$$ is:
