 tWhat's the questuon??

 

If you want to know the straight-line distance from the starting point to the terminating point, we can use the Law of Cosines to find this......we have

 

d^2 = 210^2 + 98^2 -2(98)(210)cos 135

 

d = sqrt (210^2 + 98^2 - 2(98)(210)cos 135  = about 287.76 km

 

 

 

cool cool cool
