Answer:
x = 5
Step-by-step explanation:
In order to obtain a solution, we must assume that the figure is a parallelogram.
Angle BED will be congruent to angle BCD. The sum of angles in triangle BED is 180°, so we have ...
55° +51° +(14x +4)° = 180°
14x = 70 . . . . . . divide by °, subtract 110
x = 5 . . . . . . . . . divide by 14
(2, 0°) is already in polar coordinates, with the smallest possible angle. The radius is 2, always 2. Expressions with variations of the angle are also good representations of (2, 0°) if their angles are all integer multiples of 360 degrees. For example: (2, 720°) represents the same point in polar coordinates as does (2, 0°).
