Question
Determine the direction in respect to the positive X axis of the resultant vector from the sum of the vectors A+B+C if:
A= 2.00i + 4.00j
B= 1.00i - 6.00j
C= -8.00i + 8.00j
A= 2.00i + 4.00j
B= 1.00i - 6.00j
C= -8.00i + 8.00j

A+B+C
= -5i + 6j = <-5,6>
tan (theta) = - 6/5 in quadrant II
so theta = appr 130°
= -5i + 6j = <-5,6>
