Sir Mike Ambrose is the author of the question. Let c be 4 units. Therefore; b is; 2cos(25)+2cos(25)tan(65/2) b = 2.96737905059 units. a is; 2sin(65)-2sin(65)tan(65/2) a = 0.65785209755 units. It implies; (a+b) ÷ c in decimal is; (0.65785209755+2.96737905059) ÷ 4 = 3.62523114814 ÷ 4 = 0.90630778704 ≈ 0.91 to 2 decimal places.

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 = 4.64101615138 cm. sin60 = 10(2√(3)-3)/c c = 20(2-√(3)) cm. Where c is CQ. d² = 10²+(10(2-√(3)))²-20*10(2-√(3))cos60 d = 8.96575472168 cm. Where d is AS. (8.96575472168/sin60) = (10(2-√(3))/sine) e = 15° Where e is angle PAS. f = 180-60-15 f = 105° Where f is angle BSA. g = 105-90 g = 15° Whe...

Sir Mike Ambrose is the author of the question. (a) Area yellow exactly in decimal cm² is; Area triangle with height 25.2274259042 cm and base 14.5sin(½atan(20/21)) cm = ½*25.2274259042*14.5sin(½atan(20/21)) = 67.9269230771 cm² (b) Let beta be y. Therefore; y = 90 - (atan(20/21) + ½(atan(20/21))) y = ½(180 - (3atan(20/21)))° y = 24.595771541° It implies; Tan(y) exactly in decimal is; Tan(½(180 - (3atan(20/21)))) = Tan(24.595771541) = 0.45774647887
