So the photo is a little bit blurry, but from what I can make out, you seem to be on the right track. Some things to keep in mind when determining the systematic name of the coordination compound is to first identify the central atom (in this case cobalt), then determine the ligands and their names (which are ammonia and chloride), then write the ligands in alphabetical order (ammonia before chloride), indicate the number of each ligand using Greek prefixes (three ammonia ligands so "tri" for NH3 and three chloride ligands so "tri" for Cl-), and lastly name the central metal atom (cobalt). Hope this helps a bit!
