Answer to Question 1

.E

Answer to Question 2

Astronomers can find the inclination of a visual binary system because they can see the shape of the orbits. In a spectroscopic binary system, however, the individual stars are not visible, so the orbits can't be mapped and the inclination can't be found. In eclipsing binary systems the inclination is edge-on.
