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 the sin of 163?

What is the value of 40 degrees?
It is:- sin(40) = 0.6427876097
What is the co-function of sin 19 degrees?
cos 71
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)

What is sin 57 degrees?
The sine of 57 degrees is approximately 0.8387.
What is -40 degrees Fahrenheit in degrees celsius?
-40 degrees Fahrenheit is equal to -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
What is the sin theta of 30 degrees?
Sin theta of 30 degrees is1/2
Prove that sin 90 equals cos 50sin 40- cos 40 sin 50?
Sorry, but cos(50)sin(40) - cos(40)sin(50) is -0.1736, which is not even close to sin(90) which is 1.This does not work in radians, either. Please restate your question.
Sin equals 0.9?
If sin(theta) is 0.9, then theta is about 64 degrees or about 116 degrees.
