Mathematics Question and Solution
a² = 11*11+10*10-2*11*10cos50
a = 8.92113926968 cm.
(8.92113926968/sin50) = (10/sinb)
b = 59.16920318624°
c = 180-50-59.16920318624
c = 70.83079681376°
d = 0.5a
d = 4.46056963484 cm.
e² = 4.46056963484²+5.5²-2*4.46056963484*5.5cos59.16920318624
e = 5 cm.
(5/sin59.16920318624) = (5.5/sinf)
f = 70.83079681376°
g² = 4.46056963484²+5²-2*4.46056963484*5cos70.83079681376
g = 5.5 cm.
(5.5/sin70.83079681376) = (5/sinh)
h = 59.16920318624°
i = 180-59.16920318624-70.83079681376
i = 50°
(j/tan(0.5*70.83079681376))+(j/tan25) = 5
j = 1.40811631508 cm.
sin25 = 1.40811631508/k
k = 3.33188705401 cm.
l = 25+70.83079681376
l = 95.83079681376°
m = 25+59.16920318624
m = 84.16920318624°
Area Maroon in cm² to 1 decimal place is;
0.5*4.46056963484*3.33188705401sin95.83079681376+0.5*4.46056963484*3.33188705401sin84.16920318624
= 14.78522130837 cm²
≈ 14.8 cm²
