<–102, 117.4>
<–117.4, 102>
<–50.5, 58.1>

Answer 1

Hint:

x = r*cos(theta)
y = r*sin(theta)

Answer 2

what is r

Answer 3

it's the length of the vector

Answer 4

okay so 77?

Answer 5

yes

Answer 6

the angle theta is how much you've rotated the vector (starting at the positive x axis)

Answer 7

and going counterclockwise

Answer 8

okay?

Answer 9

so how much is this rotation

Answer 10

theres the xy axis

Answer 11

add on the vector

Answer 12

what is this angle of rotation
