Answer: m=6.2, direction is 57.84 degrees north of east
Explanation:
Break up each into x and y parts of the vector
first part only has a y
<0, 4.5>
2nd <2, 0>
3rd use trig
sin 30 = y/1.5
y=.75
cos30 =x/1.5
x=1.3
<1.3, .75>
Add all x's and y's
<3.3, 5.25> to find magnitute use pythagorean
m²=3.3²+5.25²
m=√38.45
m=6.2
to find direction use trig again
tan∅=5.25/3.3
∅=57.84
