It is by definition.
c = a X b is called the cross product of a and b vectors.
Cross product is defined as the vector c whose direction is perpendicular to a and b both. Its direction is perpendicular to the plane of a and b.
Its magnitude is given by |a| |b | Sin Ф, where Ф is the angle between vectors.
Direction is given by curling the right hand fingers from direction of a to b, then the thumb points to the direction of c.
