Respuesta :
Ann walks 80 meters with a direction of 33° north of east starting. This corresponds to a vector of
r = 80 m and θ = 33°
You draw this by making a coordinate system, two lines perpendicular to each other with the intersection as the origin. Next, locate the ray that would correspond to the direction of 33° north of east. On that ray and starting from the origin, measure 80 m or use a scale.

Answer:
Anna's walk as a vector representation is [tex]80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}[/tex] and refer attachment.
Step-by-step explanation:
Let the origin be the point 1 from where Ann start walking.
Ann walks 80 meters on a straight line 33° north of the east starting at point 1 as shown in figure below,
Resolving into the vectors, the vertical component will be 80Sin33° and Horizontal component will be 80Cos33° as shown in figure (2)
Ann walk as a vector representation is [tex]80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}[/tex]
Thus, Anna's walk as a vector representation is [tex]80\cos 33^{\circ}\hat{i}+80 \sin33^{\circ}\hat{j}[/tex]
