tan30 = a/(2√(3))
a = 2 units.
b = (2√(3)-2) units.
tan30 = c/(2√(3)-2)
c = ⅓(6-2√(3)) units.
d = 2√(3)-⅓(6-2√(3))
d = ⅓(6√(3)-6+2√(3))
d = ⅓(8√(3)-6) units.
It implies;

Let P be 2^(x)
(P⁹/8192)-256P⁶ = 0
Let y be P³
(y³/8192)-256y² = 0
y³-2097152y² = 0
y = 2097152
P³ = y
P³ = 2097152
P = 128
2^(x) = P
2^(x) = 128
2^(x) = 2^(7)
x = 7

Let AB be 4 units.
BC = 6 units.
Let a be the side length of the inscribed square.
Calculating a.
b² = 4²-a²
b = √(16-a²)
It implies;
a = √(16-a²)
6 = 4

Radius of the ascribed circle is 13 cm.
a = acos((2*13²-24²)/(2*13²))
a = 134.76027010392°
b = ½(a)
b = 67.38013505196°
c = 40°
d = b - c
d = 27....
Le the side of the regular hexagon be 1 unit.
cosa = 0.5/1
a = 60°
b = 60-36
b = 24°
c = 108-24
c = 84°
Therefore;
The required angle, x is;
½(180-84)
= ½(96)
= 48°
