If $\overrightarrow{AB} = \overrightarrow{b}$ and $\overrightarrow{AC} = \overrightarrow{c}$, then the length of the perpendicular from A to the line BC is

Question

$\frac{|\overrightarrow{b} \times \overrightarrow{c}|}{|\overrightarrow{b} + \overrightarrow{c}|}$

$\frac{|\overrightarrow{b} \times \overrightarrow{c}|}{|\overrightarrow{b} - \overrightarrow{c}|}$

$\frac{|\overrightarrow{b} \times \overrightarrow{c}|}{2|\overrightarrow{b} - \overrightarrow{c}|}$

$\frac{|\overrightarrow{b} \times \overrightarrow{c}|}{2|\overrightarrow{b} + \overrightarrow{c}|}$
