Answer:
C. 4(cos(300°) +i·sin(300°))
Step-by-step explanation:
The magnitude will be ...
magnitude = √(2^2 +(-2√3)^2) = √(4+12) = 4
The negative imaginary part puts the angle in the 4th quadrant. The answer choice with a magnitude of 4 and a 4th-quadrant angle is ...
4(cos(300°) +i·sin(300°))
__
If you want to figure the angle, it will be ...
angle = arctan(Im()/Re()) = arctan(-2√3/2) = arctan(-√3) = -60°
The corresponding 4th-quadrant angle is 300°.

<em>Comment on answer choices</em>
Answer choice A is <em>another representation of the same number</em>. Typically, we want the magnitude to be positive in polar form, so that answer can be avoided on those grounds.

Step-by-step explanation:
400,200,100,50,25,12.5, ...... 0.78125
Answer:
14°
Step-by-step explanation:
Both angles are vertical angles and are opposite, hence, from angle theorem., vertically opposite angles are equal :
Angle EGD = Angle FGH
Angle EGD = (4x + 8)
Angle FGH = 64
HENCE,
4x + 8 = 64
4x = 64 - 8
4x = 56
x = 56/4
x = 14°
