In navigation, a heading is given as the angle measured clockwise from vertical. the component form for the velocity vector for an airplane flying a heading of 170 degrees at 460 mph

170° clockwise from vertical is actually 280° as vectors are measured (counterclockwise from positive x-axis).

Therefore, component form is <460cos280°, 460sin280°>
= <798.88,-453.01> ( B.)

B.the point lies directly on the regression
