Since 210=180+30, we have

\cos(210)=-\cos(30)=-\dfrac{\sqrt{3}}{2}

\cos(210)=-\sin(30)=-\dfrac{1}{2}

So, we have

z=2\left(-\dfrac{\sqrt{3}}{2} - \dfrac{i}{2}\right) = -\sqrt{3}-i

The area of a playground is 216 yd^2. The width of the playground is 6 yd longer than its length. Find the length and width of t
zvonat [6]

Let the length of the playground be x, then the width is 6 + x.

Area = length * width = x * (6 + x) = 6x + x^2 = 216

Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18

i.e length = 12 and width = 6 + 18 = 18
