Let AB equal 1 unit. (1/sin60) = (a/sin20) a = 0.39493084363 units. a is BC. (1/sin60) = (b/sin100) b = 1.1371580426 units. b is AC. (1.1371580426/sin110) = (c/sin10) c = 0.21013831273 units. c is CD. (BD)² = 0.21013831273²+0.39493084363²-2*0.21013831273*0.39493084363cos120 BD = 0.53208888623 units. (0.53208888623/sin120) = (0.21013831273/sind) d = 20° d is angle CBD. Therefore the required angle x is; 100-d x = 100-20 x = 80°

Let a be 1 unit. (1/sin9) = (b/sin36) b = 3.75738972957 units. (AB)² = 3.75738972957²+1-2*3.75738972957cos135 AB = 4.52014702134 units. (4.52014702134/sin135) = (f/sin18) f = 1.97537668119 units. (4.52014702134/sin135) = (e/sin27) e = 2.90211303259 units. Observing the proof. Notice; a = 1 unit. b = 3.75738972957 units. e = 2.90211303259 units. f = 1.97537668119 units. It implies; (e/a)-(b/f) = 1 (2.90211303259/1)-(3.75738972957/1.97537668119) = ? 2.90211303259-1.90211303259 = 1 Pro...

Let the square side be 2a units. b² = (2a)²+a² b = √(5a²) b = √(5)a units. cos(atan(½)) = c/a c = ⅕(2√(5))a unit. d = b-c d = √(5)a-⅕(2√(5))a d = ⅕(3√(5))a units. Calculating a. 1 = a²+ (⅕(3√(5))a)²-2a(⅕(3√(5))a)cos(180-atan(2)) 1 = (14a²/5)+(6a²/5) 14a²+6a² = 5 20a² = 5 a = ½ units. 2a (the square side length) = 1 unit. (1/sin(180-atan2)) = (0.5/sine) e = 26.56505117708° f = 180-(180-atan(2))-26.56505117708 f = 36.86989764584° g = 90-36.86989764584 g = 53.13010235416° h = atan(2)°...

Biggest square side is 14 units. Bigger square side is 8 units. a = atan(9/16) (9/16) = b/c c = (16b/9) units. (16b/9)+6 = 14 (16b/9) = 8 b = (9/2) units. c = (16*9/2)/9 c = 8 units. d = 9-b d = (9/2) units. Where d is the side length of the big square. Or (9/16) = d/8 d = (9/2) units. (e/sin(atan(9/16))) = (8/sin(180-atan(9/16)-atan(9/6)) e = 12√(13)/11 units. f² = e²+(9/2)²-9ecos(90+atan(2/3)) f = 7.44025792675 units. (7.44025792675/sin(90+atan(2/3)) = (3.93332866414/sing) g = 26....
