Answer:

(-2 sqrt(3), 2)

Step-by-step explanation:

It is looking for a coordinate on a rectangular plane.

4(cos(150)+<em>i</em>sin(150))

x = rcosθ; y = rsinθ

For X:

x = 4cos(150);

x = 4 * -sqrt(3)/2; \

x = -2sqrt(3)

For Y:

y = 4sin(150)

y = 4 * 1/2

y = 2

Then you just put it as (x, y) with out <em>i</em>

(2sqrt(3), 2)

I also took the test on a p e x
