A boat in the calm seas travels in a straight lir and ends the trip 22 km west and 53 km nort of its original position. To the nearest tenth of degree , find the direction of the trip. Assume the start is at (0,0 ) The end is at (-22,53 ) . direction =tan^ ^ -1(-53/22)=-67.46 But the angle is in the 2nd Quadrant. So, direction ion = - 67.46 + 180 = 112.54 degree Cheers Stan H.
