Same with problem https://www.physicsforums.com/threads/trigonometric-problem.76696/ . My problems here is I cannot came up with the same answers in the book. I didn't solve using vectors.

2. Relevant equations
I would like to know the equation on the 4th hint although I have different solution. It might help me get to the answers.
3. The attempt at a solution
The attempt solution is attached on this post.
I have the values of radial velocity and transverse velocity but I cannot came up with the answers 12.26 (a) 5770 m; (b) 263 m/s; (c) 18.86◦ (for B and C).

I would be inclined to use cartesian coordinates.

Let x(t) = horizontal location of plane relative to A
Let x(t) - 1000 = horizontal location of plane relative to B
Let y(t) = vertical location of plane
