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:
Xcomponent of resultant
= ∑Di*cos(θi)
and
Ycomponent of resultant
= ∑Di*sin(θi)
D(1)=145m, θ(1)=9020=70° (from xaxis)
D(2)=105m, θ(2)=35° (from xaxis)
