I am so desperate that I have decided to post my question here. I've been searching on Google and Youtbe but nothing really helped me.

Here is my question.

One ship (A) Bobby is sailing calm seas at a speed (relative to the surrounding sea) of 30km on bearing of 40(degree) and another ship (B) Tom sailing calm seas at a speed (relative to the surrounding sea) of 35km on a bearing of 130 (degree). Ship (B) cross the path of ship (A) at right angle.

Question: express in component form velocity for ship (A) Bobby and velocity for ship (B) Tom, both relative to the sea, give the numerical values in km to two decimal points.

Can someone explain give an clear guidance of how to solve this question ?

I supposed to draw a diagram as well (triangle).

I will really appreciate it.

kind regards
