How Do You Solve Vector Addition Problems?

[Bensky]

Need MORE help with vectors by tomorrow. :(

Homework Statement

Attached in the picture. C can be moved around in all different directions and can rotate since it is supposed to be R, the other two can only be moved horizontally and vertically.

Homework Equations

C = A + B

The Attempt at a Solution

I tried a number of different ways using the tail to tip method. It didn't show me my previous responses like the other problems, so unfortunately I can't show which ones I tried. :(

What are you trying to find? The components of C? What is the problem ?

I'm trying to put A, B, and C in the correct positions to show a vector sum. C = Resultant.

Ah! Ok, A + B = C So, use the tail-to-tip method, that is, the tip of A must be at the tail of B, then the tail of C starts at the tail of A and goes to the tip of B. Can you see why this must be so?
