Dear Shivanshi,

 I can suggest u a method to solve this problem. Consider the nitrogen molecule as a origin and we know the angles of the pyramid for the ammonia molecule and also they provided data related to the distance of the centre of the pyramid which is the centroid of the tetrahedron and using these data and geometric relations for 3 D geometry we cansolve this problem.
