classes are arranged in a school compound.jss1 is 4km due east of jss2,jss3 is 3km south of jss1 and ss1 is 4km at a bearing of 230 from jss3.calculate the distance and bearing of jss2 from ss1

Hmmm. If jss3 is south of jss1, then jss1 cannot be on a bearing of 230° (basically southwest) from jss3.
