A jogger runs 145m. in a direction 20.0 degrees east of north (displacement of vector A) and then 105m. in a direction 35.0 degrees south of east (displacement of vector B). Using components, determine the magnitude and direction of the resultant vector C for these two displacements.

Hints:

X-component of resultant

= ∑Di*cos(θi)

and

Y-component of resultant

= ∑Di*sin(θi)

D(1)=145m, θ(1)=90-20=70° (from x-axis)

D(2)=105m, θ(2)=-35° (from x-axis)
