John, Paul, and George are standing in a strawberry field. Paul is 16.0m due west of John. George is 40.0m from Paul, in a direction 38.0 degrees south of east from Paul's location.

How far is George from John?

What is the direction of George's location from that of John?

Alright so where do I begin? :X

It must indeed be a triangle, but is it a right triangle?

Correct, oldspice. The example demonstrates the right triangle.

Now, let's get back to the problem you need help with.

John, Paul, and George are standing in a strawberry field. Paul is 16.0m due west of John. George is 40.0m from Paul, in a direction 38.0 degrees south of east from Paul's location.

How far is George from John?

What is the direction of George's location from that of John?

Try drawing the vector diagram similar to the given figures one user showed to you, according to the info given.
