Answer:

How else but by VESPER?

Explanation:

For both #NH_3# and #BF_4^(-)# electronic geometry is TETRAHEDRAL to a first approximation. For #BF_4^(-)#...molecular geometry is TETRAHEDRAL...and #/_F-B-F-=109.5^@#...

For ammonia, the lone pair of electrons influences molecular geometry. #NH_3# is trigonal planar with #/_H-N-H-=104.5^@#, i.e. compressed slightly with respect to the tetrahedron.
