Learning Goal: To be able to add and subtract vectors using geometric and vector addition. A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d₁ = 23.5 m at 0₁ = 24.5° from the tree then turned and traveled d₂ = 12.0 m at 02132°.

A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a
particularly large tree. The brother traveled d₁ = 23.5 m at 0₁ = 24.5° from the tree then turned and traveled d₂ = 12.0 m at 02132°. Meanwhile, the
sister traveled d3 = 18.5 m at an angle of 63 -113° from the tree. The angles are given with respect to east with counterclockwise being defined as
positive
