WebTake the cos of the angle and multiply it by the magnitude to get the x value (rounding it to the nearest thousandth) and use sin for the y value but do the same thing. Example: A complex number z₁ has a magnitude z₁ = 20 and angle θ₁ = 281° Express z₁ in rectangular form, as z₁ = a + bi. Round a and b to the nearest thousandth.
