What is the area of a triangle with angles of 50 60 and 70 degres when the radius of its circumcircle is 10cm?
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
What is the perimeter of an equilateral triangle whose area is 97.428 square cm showing work and answer to the nearest integer?
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
What is the area of an equilateral triangle with a side of 5m?
Area = 0.555*sin(60) = 10.825 square m to 3 decimal places
What is the area of a triangle if all sides are 30ft?
Area = 0.5*302*sin(60) = 389.711 square feet to 3 decimal places
What is the area of an equilateral triangle of side 20cm?
Area = 0.5*20*20*sin(60) = 173.205 square cm to 3 decimal places
What is sin 60 degrees?
square root 3/2
Solve sin x square root of 3 by 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
What is sin 60?
square root of three over two
Why is sine 30 the same as cosine of 60?
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
What are the lengths of each side of an equqilateral triangle if the surface area is known to be 2500?
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
What is the area of a triangle with angles of 50 60 and 70 degres when the radius of its circumcircle is 10cm?
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
What is x if the Sin of x equals square root 3 divided by 2?
1.5
What is the sin 60?
sin 60 = √(3)/2 or about 0.866 ■
What is the perimeter of an equilateral triangle when its area is 692.820323 square cm?
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
What is the perimeter of an equilateral triangle whose area is 97.428 square cm showing work and answer to the nearest integer?
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
What is the area of an equilateral triangle with a side of 5m?
Area = 0.555*sin(60) = 10.825 square m to 3 decimal places
What is the area of an equilateral triangle whose perimeter is 22.5 cm?
It is: 0.5*7.5 square*(sin 60 degrees) = 24.357 square cm rounded up to 3 d.p.
