Quadrilaterals ...

In a quadrilateral $$ABCD$$, if $$\angle$$ $$A = 60$$ $$^o$$ and $$\angle$$ $$B :$$ $$\angle$$ $$C :$$ $$\angle$$ $$D = 2 : 3 : 7$$, then $$\angle$$ $$D =$$ ?

The angles of a quadrilateral are in the ratio $$3 : 5 : 9 : 13$$. Find all the angles of the quadrilateral in degrees.

If three angles of a quadrilateral are of magnitudes $$80^\circ,\ 95^\circ,\ 120^\circ,$$ then what is the measure of the fourth angle?
