A sailboat race course consists of four legs, defined by the displacement vectors A→, B→, C→, and D→, as the drawing indicates. The magnitudes of the first three vectors are A = 3.70 km, B = 4.70 km, and C = 4.60 km. The finish line of the course coincides with the starting line. Using the data in the drawing, find (a) the distance of the fourth leg and (b) the angle θ. (a) Number Units (b) Number Units

The route followed by a hiker consists of three displacement vectors A→, B→, and C→. Vector A→ is along a measured trail and is 1510 m in a direction 21.0∘ north of east. Vector B→ is not along a measured trail, but the hiker uses a compass and knows that the direction is 17.0∘ east of south. Similarly, the direction of vector C→ is 32.0∘ north of west. The hiker ends up back where she started, so the resultant displacement is zero, or A→ + B→ + C→ = 0. Find the magnitudes of (a) vector B→ and (b) vector C→. (a) Number Units (b) Number Units
