(1) Not Sufficient
(2) Not Sufficient
Combined :
We we know that C angle is 30 , thus if we make right triangle out of this picture we get 30:60:90 triangle , and since we know BC , we know everything!

A few points need to be thought out not necessarily worked out
ABC is a isosceles triangle
The perpendicular from A on BC bisects the base say at point X.
angle CAX = BAX = 60°.
CX = BX = sq rt of 3
