Answer:
Explanation:
The cartesian coordinates is (-2, 2)
So, x = -2 and y = 2
So, r Cos θ = x and r Sin θ = y
r Cos θ = - 2 .... (1)
r Sin θ = 2 .... (2)
Squarring equation (1) and (2) and add


r = 2.83
Divide equation (2) by equation (1), we get

θ = 3π/4
So, the polar coordinates are (2.83 Cos 3π/4, 2.83 Sin 3π/4)
