31.3 km in a direction φ = 61.2◦ west of north.

Find the magnitude of the car’s resultant

displacement.

Then Calculate the direction of the car’s resultant displacement, measured counterclockwise from the northerly direction.

Cosine Law

d=sqrt{20.2²+31.3²-2•20.2•31.3•cos118.8°} =

=44,7 km

Sine Law

31.3/sinθ=44.7/sin118.8°

sinθ=31.3 •sin118.8°/44.7=0.61

θ= 37.9°
