Calculating Angle x.a+30+20+20 = 180a = 180-70a = 110°Let 1 unit be the radius of the circle.cos20 = b/1b = cos20b = 0.93969262079 units.c = 2bc = 1.87938524157 units.1.87938524157/sin110 = d/sin40d...
Sir Mike Ambrose is the author of the question.Area blue exactly in cm² is;Area triangle with height (2√(13)-2) cm and base (4sin120) cm.= ½*(2√(13)-2)*(4sin120)= √(3)(2√(13)-2)= 2(√(39)-√(3)) cm²
Calculating Area Yellow Inscribed Trapezoid.(2√(2)/sin135) = (√(2)/sina)a = 20.70481105464°b = 180-20.70481105464-135b = 24.29518894536°(c/sin24.29518894536) = (2√(2)/sin135)c = 1.64575131106 units.W...
Calculating Area Yellow.Notice.The ascribed quadrilateral is a square with side 6 units.a² = x²+3²a = √(x²+9) units.b = 2ab = 2√(x²+9) units.c = (6+x) units.Notice.b = cTherefore, calculating x.2√(x²...
