Question

Why do I not understand this?! Am I on the right track? I want to try to do it by my self, but I would like some guidance, please.

Answer 1

Step-by-step explanation:

You are close.  When calculating the radius and angle, you use the magnitudes of the real and imaginary terms.  In other words, you leave out the i in the calculation.

r = √((-8)² + (√3)²)

r = √(64 + 3)

r = √67

θ = π + atan((√3) / (-8))

θ ≈ 2.928
