9. (10 pts) An airplane proceeds at a bearing of $30E, flying at 540 miles per hour. (no explanations required) (a) State the angle o in standard position which corresponds to the bearing $30 E. (b) Find the easterly and southerly 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
