PLEASE HELP!

i am sure, a would be done by you, if not then temme..
here is b)
For the one triangle BXC :
The area of segment formula u found out in a(ii) use that to find the area of segment BC with r = 4 and alpha = pi/6 = 8pi/3 - 4sqrt(3)
The area of triangle BXC = {1/2 * 2 * 2sqrt(3)/3 } * 2 = 4sqrt(3)/3
The shaded region BXC = area of triangle BXC - Area of segment BC = 16sqrt(3)/3 - 8pi/3

The shaded area BXC = shaded area AXC = shaded area AXB

Therefore total shaded area = 3 * shahded region BXC = 16sqrt(3) - 8pi

Can you explain why √3/3
I'm stuck on that part

I'm stuck on that part

exact value of tan π/6 is √3/3

Thanks . I thought it had something to do with special angle since 1/6π is 30°
Thank you so much
