Consider the following statements:Statement I: If the line segment joining the points P (m, n) and Q(r, s) subtends an angle α at the origin, then $\cos \alpha = \frac{{ms - nr}}{{\sqrt {\left( {{m^2} + {n^2}} \right)({r^2} + {s^2}} }}$Statement II: In any triangle ABC, it true that a2 = b2 + c2 – 2bc cos A.Which one of the following is correct in respect of the above two statements?
