Calculating Area Yellow.a = ½(180-30)a = 75°2² = b²+1²b² = 4-1b = √(3) units.Yellow Area is;2(Area triangle with height √(3) units and base 1 unit + Area sector with radius 2 units and angle 60° - Ar...
Sir Mike Ambrose is the author of the question.Let the single side length of the square be 2 units.Therefore;Area square is;2²= 4 square unitsIt implies;Area R is;Area sector with radius 2 units and...
Calculating Length CD.a = 15-11.25 a = 3.75 m.b = atan(3/3.75)°c = 90-atan(3/3.75)c = 51.34019174591° Therefore, Length CD is;tan(51.34019174591) = 15/CDCD = 15/tan(51.34019174591) CD = 12 m.
Calculating Blue Area.Area blue is;Area sector with radius 10 cm and angle 2atan(½) - Area triangle with height 10 cm and base 10sin(2atan(½)) cm + Area sector with radius 5 cm and angle 2atan(2) - A...
Sir Mike Ambrose is the author of the question.Inscribed square single side length is;7.80540954246 cmArea green in cm² to 1 decimal place is;Area trapezoid with parallel sides 12 cm and 7.2594829122...
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...
