1.A person of dubious technical ability tells you that two of the direction angles for a particular vector are 30 and 40 degrees. If these direction angles are feasible, then determine the possible values for the remaning direction angle. If these direction angles are not feasible, explain why?
2.Given a potentiometric surface with a regional slope of 7m/km, calculate the natural rate of groundwater discharge through a confined aquifer with transmissivity (hydraulic conductivity times aquifer thickness) of 0.002 m2/s.
