Effects on labor.

Problem: Consider the example of 2 vectors, R = A + B has a cos37 and sin37.

To find the result .. First I shall present the results of Ax and Bx Rx and then use Ay & Ry.

Rx = Ax + Bx
Rx =- 12N + 14.4
Rx = [2,4]

* I understand why Ax is -12, because it is on the left side ... How do I know that 14.4 is the Blessed?
