1.	In the adjoining figure, O is the centre of the circle and PQ, RS are its equal chords, OD⊥PQ and OE⊥RS . If ∠DOE=130∘ then find ∠PDE
Answer» In the adjoining figure, O is the centre of the circle and PQ, RS are its equal chords, $O D ⊥ P Q$ and $O E ⊥ R S$ . If $∠ D O E = 130^{\circ}$ then find $∠ P D E$
