Let a ber the radius of each of the two congruent circles.
b = (a+29) units.
b is the side length of the square.
c² = 2*29²
c² = 1682
c = 29√(2) units.
Calculating a.
It implies;...
Calculating green area.
a² = 2²+2²
a = √(8)
a = 2√(2) units.
sin30 = b/a
½ = b/(2√(2))
b = √(2) units.
c²+b² = a²
c²+√(2)² = (2√(2))²
c² = 8-2
c = √(6) units.
Area green is;
(...
Let the base of the quadrilateral be 1 unit.
a = -54-18+180
a = 108°
(1/sin108) = ((b/sin18)
b = 0.3249196962 units.
Therefore, area B is;
0.5*1*0.3249196962sin54
= 0.131432778 squar...
Let c be the radius of the ascribed half circle.
d² = 2c²
d = √(2)c cm.
d is the diameter of the inscribed half circle.
e = ½(d)
e = ½(√(2)c) cm.
e is the radius of the inscribed half circ...
13² = 20²+11²-2*20*11cosa
169 = 521-440cosa
440cosa = 521-169
cosa = 352/440
a = 36.8698976458°
(13/sin36.8698976458) = (11/sinb)
b = 30.5102374061°
c = 180-a-b
