Three-Step Processes of Geometric and Vector Addition 8 of 19 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 d, 24.0 m at e,20.5° from the tree then turned and traveled d 11.0 m at 8 133°. Meanwhile, the sister traveled ds 19.0 m at an angle of 8,-111° from the tree. The angles are givern with respect to east with counterclockwise being defined as positive(Figure 1) Part A -Position of the boy Using the parallelogram law to add these vectors geometrically, determine the displacement of the boy relative to the tree.(Figure 2) Express your answers, separated by a comma, to three significant figures. Enter the angle measured counterclockwise from the positive x axis.
