A bird flies 100 m due east from a tree, then 200 m northwest and lands atop a telephone pole. Place an XY-coordinate system so that the origin is the tree, the X-axis points east, and the Y-axis points north.

(a) Use algebraic addition to find the bird's net displacement.

(b) Use a graphical method to find the bird's net displacement.

Determine solutions of graphical examples using the geometry and vector methods. Don't ues notebook because i don't understend some people handwriting thanks.
