1. Homework Statement
Given the two vectors in the diagram, calculate their magnitudes if A+B-225j=0
Homework Equations
sum of x component= Acos(42)--Bcos(56)
sum of y component= Asin(42)+Bsin(56)--225j
The Attempt at a Solution
Find A and B use substitution
A= [Bcos(56)]/cos(42) from x comp.
plug that into y comp. to solve for B
[Bcos(56)sin(42)]/cos(42) + Bsin(56) -- 225j=0
After solving, I got B= 168.85 and A=127.05. Does that seem correct?
