9. (10 pts) An airplane proceeds at a bearing of N60 E, flying at 540 miles per hour. (no explanations required) (a) State the angle - in standard position which corresponds to the bearing N60 E. (b) Find the easterly and northerly components of the airplane's velocity. That is, find the component form of the vector which has a magnitude of 540 and makes the angle o with the positive x-axis. (Use the value of o you stated in part (a).) State the exact values and also give approximations to the nearest mile per hour
