If you see something like AX3E, that means that there are three atoms/molecules surrounding a central atom as well as one lone pair, meaning trigonal pyramidal.
A represents the central atom, X represents bonded atoms, and E represents lone pairs. The subscripts represent how many of each of these there are, and A will never have a subscript.
