A rocket flies 150 km on a bearing of 042 degrees. It then flies 45 km on a bearing of 165 degrees. Find

a. The bearing
b. The distance of the rocket from the starting point?

1 answer

(a) convert to x-y, add the components, then find the bearing by arctan of displaceement
(b) The distance z is found via
z^2 = 150^2 + 45^2 - 2*150*45*cos57°
