Consider the two vectors A = 3 ihat − 3 jhat and B = − ihat − 4 jhat .?
Consider the two vectors A = 3 ihat − 3 jhat and B = − ihat − 4 jhat .
Calculate the directions of A + B and A − B.
A + B ° (counterclockwise from the +x axis)
A -- B ° (counterclockwise from the +x axis)

What is the i-component of B? - ihat suggests -1, so that's what I'll use.
A + B = 2 i - 7 j → Θ = arctan(-7/2) = -74º = 286º
A - B = 4 i + 1 j → Θ = arctan(1/4) = 14º
Assuming this became right into a wand with limitless supplies, i'd exchange my homestead right into a mansion with servants to do each and every thing for me. i'd exchange the measly volume in my checking accound into an limitless furnish of money, and that i'd bypass out and initiate working at something of the worldwide to make issues great for each individual else.
