A, B and CÂ are three points on a circle such that the angles subtended by the chords AB and AC at the centre O are $$80^\circ$$Â and $$120^\circ$$, respectively. The value of $$\angle BAC $$ is:
if $$0 < A, B < 45^\circ, \cos(A + B) = \frac{24}{25}$$ and $$\sin(A - B) = \frac{15}{17}$$, then $$\tan 2A$$ is
