Vector resolution onto axes not at right-angles

[AzureSekki]

Summary:: I'm quite stuck on this problem i don't know what I am going to use formula to solve this one

This is the given I am not sure if this is a resolution problem or it involve parallelogram law

Welcome to PF. I moved your post to a homework forum because it looks like homework.

Why did you post the pictures sideways?

Our homework help rules require you to show your effort before our helpers can help. Show us how you would calculate the two components asked for.

This is my current solution but the key answers were given to us except for the solution
The key answers were
2224 ft and 2551 ft
Most of my answers are faraway from the key answers that why I am quite stuck

You are incorrectly mixing the angle of 65 degrees with the OA vector.
It indicates the angle of the OB component of that vector instead.

Can you elaborate much further in where i got wrong

Not really.
Draw a line that being parallel to OB, goes between A and the intersection point with OC.
In a triangulation diagram, that will be one of the components of vector OA.
The other component will be the line between that intersection point and O.
Try to draw that set of triangles and resolve for magnitudes of both components.
Good night.

Is this what u meant

I got the answer thanks

I got the answer thanks

Excellent!
Could you show your work and final values?
What method did you use?
