From the given information and transposing the relevant formulae its area works out as 200*sin(50)*sin(60)*sin(70) = 124.6810383 or about 125 square cm
Let the sides be s:- If: 0.5*s squared*sin(60 degrees) = 97.428 Then: s = square root of 97.428*2/sin(60 degrees) => 15.00001094 Perimeter: 3*15 = 45 cm
Area = 0.555*sin(60) = 10.825 square m to 3 decimal places
Area = 0.5*302*sin(60) = 389.711 square feet to 3 decimal places
Area = 0.5*20*20*sin(60) = 173.205 square cm to 3 decimal places
square root 3/2
Do you mean sin(x)=sqrt(3)/2? IF so, look at at 30/60/90 triangle. We see the sin 60 degrees is square (root of 3)/2
square root of three over two
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
Area of an equilateral triangle = 1/2*a2*sin(60) 1/2*a2*sin(60) = 2500 square units Making 'a' the subject of the equation will give the length of each side. a = 75.98356857 Check: 0.5*75.983568572*sin(60) = 2500 square units

sin 60 = √(3)/2 or about 0.866 ■
1 Let each side be s 2 If: 0.5*s2*sin(60) = 692.820323 square cm 3 Then: s = square root of (692.820323*2)/sin(60) = 40 cm 4 Perimeter: 3*40 = 120 cm
Let the sides be s:- If: 0.5*s squared*sin(60 degrees) = 97.428 Then: s = square root of 97.428*2/sin(60 degrees) => 15.00001094 Perimeter: 3*15 = 45 cm
Area = 0.555*sin(60) = 10.825 square m to 3 decimal places
It is: 0.5*7.5 square*(sin 60 degrees) = 24.357 square cm rounded up to 3 d.p.
