What is the perimeter of a regular nonagon that has an area of 395.6367484 square cm?
The regular nonagon will consist of 9 congruent isosceles triangles with base angles of 70 degrees and an apex angle of 40 degrees. Its 2 equal sides: square root of 385.6367484*2/sin(40)*9 = 11.6952176 cm Its base: sin(40)*11.6952176/sin(70) = 8 cm Perimeter: 9*8 = 72 cm
What is sin 97 degrees?
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
A right angle triangle has an angle of 16.5 degrees. and a rise of 40 feet then how many feet is the hypotenuse?
sin(angle) = opposite/hypotenuse → hypotenuse = opposite/sin(angle) opposite = rise → hypotenuse = 40ft / sin 16.5° ≈ 140.84 ft
What is the third angle of a triangle that has 100 degrees and 40 degrees?
180 degrees - 100 degrees - 40 degrees = 40 degrees

What is sin 57 degrees?
sin 57 degrees
What is the index of refraction of a material if the angle of incidence in air is 50 degrees and the angle of refraction in the material is 40 degrees?
When a ray of light passes from material 1 to material 2: N1 sin θ1 = N2 sin θ2 where N1 & N2 are the refractive indices of the materials, and θ1 is the angle of incidence, θ2 the angle of refraction. From air to the material: N1 = 1.00, θ1 = 40°, θ2 = 50°, N2 = unknown, the index of refraction of the material: → 1.00 x sin 50° = N2 x sin 40° → N2 = 1.00 x sin 50° ÷ sin 40° → N2 ≈ 1.1917 (the index of refraction of the material)

Sin theta of 30 degrees is1/2
What is -40 degrees Fahrenheit in degrees celsius?
(-40) degrees Fahrenheit = (-40) degrees Celsius.
A right angle triangle has an angle of 16.5 degrees. and a rise of 40 feet then how many feet is the hypotenuse?
sin(angle) = opposite/hypotenuse → hypotenuse = opposite/sin(angle) opposite = rise → hypotenuse = 40ft / sin 16.5° ≈ 140.84 ft
Sin equals 0.9?
If sin(theta) is 0.9, then theta is about 64 degrees or about 116 degrees.
What is the sin of 90 degrees?
sin(90) = 1
