Question

PLEASE HELP
A mouse is trapped in a maze. To find his way out, he walks 15 m, makes a 90° left turn, walks 8 m, makes another 90° left turn, and walks 10 m. What is the magnitude of the resultant vector?

Answer 1

<10, 15> + <-8, 0> + <0 , -8> + <10, 0> = <2, 7>

v = <2, 7>
||v||2 = 22 + 72
