As usual, triangle sides are named a (side BC), b (side AC) and c (side AB).
Altitude of a triangle to side c can be found as:
h_c=\frac{2S}{c}
where S - an area of a triangle, which can be found from three known sides using, for example, Hero's formula, see Calculator of area of a triangle using Hero's formula
