Question 472865: A glider lands 17 miles west and 9 miles south from where it took off. The result of the trip can be described by the vector (-17, -9). Use distance (for magnitude) and direction to describe this vector a second way.
a. about 19 miles at 28 degrees south of west
b. about 28 miles at 19 degrees north of west
c. about 19 miles at 28 degrees north of west
d. about 28 miles at 19 degrees south of west Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Ans: a
----
sqrt(17^2+9^2) = 19.24 miles
----
tan^-1(-9/-17) = 27.89 degrees in the 3rd Quadrant
