9 = 8-8cosa
8cosa = -1
a = acos(-1/8)
a = 97.18075578146°
Therefore;
a• = 180-a
a• = 180-97.18075578146
a• = 82.81924421854°
b = ½(180-82.81924421854)
b = 48.59037789073°
c = ½(48.59037789073)...
a = acos(3/5)
Where a is angle GCA.
tan(acos(3/5)) = b/3
b = 4 units.
Where b is AG.
c = atan(⅔)
Where c is angle GBE.
d = 180-acos(3/5)-atan(⅔)
d = 93.17983011986°
Where d is angle BEC.

Let the inscribed square side be a.
tan60 = a/b
a = √(3)b cm.
Where b is BS = CR
It implies;
b+√(3)b+b = 10
(2+√(3))b = 10
b = 10(2-√(3)) cm.
Therefore;
a = √(3)*10(2-√(3))
a = 10(2√(3)-3) cm.
a...

xy = 40 ------ (1).
b = 4+x-5
b = x-1
y(x-1) = 20 ------ (2).
At (1)
x = 40/y ------ (3).
Notice;
y is the length or base of the rectangle.
Substituting (3) in (2) to get y.
y((40/y)-1) = 2...
