Answer:

z = -8.46 - 3.08i.

Step-by-step explanation:

cos 200 = -0.93969 so 9 * cos 200 = -8.46 to the nearest hundredth.

sin 200 = -0.3420 so 9 * sin 200 = -3.08 to nearest hundredth.

Answer:

$\huge\boxed{\sf x = 4}$

Step-by-step explanation:

If the given polygon is a regular polygon, its sides are equal.

This means:

$x^2+4=x^2+x$

Subtract $x^2$ to both sides

4 = x

x = 4

$\rule[225]{225}{2}$
