Answer:
6
Step-by-step explanation:
A regular hexagon has six side and it is rotated counterclockwise about its center.
rotation is 0° < x ≤ 360
it will map on itself at the multiples of the angle = 360 / 6 = 60°
which are 60°, 120°,180°, 240°, 300° and 360°
the number of different angles = 6

The value of the coefficient B will be 9.
<h3>What will be the value of B in equation written below?</h3>
2(x+By)(x-2y)
=2(x^2 -2xy +Bxy -2By^2)
=2x^2 -4xy + 2Bxy - 4By^2
The original form is 

hence the value of B=9
