How do you work out angle of refraction with refractive index?
You can use Snell's Law. Note that you need two angles for this - the incoming angle, and the outgoing angle.
How Do you solve a cubic equation by trisecting an angle?
The classical problem of angle trisection cannot be solved. If it were possible, it would provide the solution to a cubic equation. (-but it isn't and it won't!)
How do you work out the length of a rectangle with the width and an angle?
It depends on what angle. The main angles of a rectangle are all 90 degrees and knowing that does not help. If however, the angle in question is the angle made by the diagonal with one of the sides, then it is possible to use a basic trigonometric ratio to work out the length. Details will depend on which angle is given.
What is the equation to find an unknown obtuse angle when only one angle is known?
you subtract the other angle from 180 and that should give you your answers
How do you find the measure of each interior angle of a regular octagon?
Use the equation 180(n-2)/n, where n is the number of sides in the figure.
How do you find the perimeter of a rectangle with a diagonal measurement and one angle?
you use SOHCAHTOA to work out whether you need to use sine or cosine (as you already have the hypotenuse) you then use the diagonal as the hypotenuse and use the equation of either: sin(angle)=missing side/diagonal cos(angle)=missing side/diagonal you then take the answer and mark it on the two sides that it applies to. you use the value you just found along with the diagonal in the Pythagoras theorem equation (in this case it will be b2 = diagonal2-other side2). you then have the value of every side so you just add them all together.
How do you find the area of an isosceles triangle with 2 equal sides and 1 angle?
It really depends on the angle. If the angle is at the point where the two equal sides intersect then you can divide the triangle into two equal parts (forming a right angle with the base), divide the angle by two, then use the following equation(side*arccos(your angle/2))*((side*arcsin(your angle/2)))if the angle is not where the two equal sides intersect then you can divide the triangle into two equal parts (from the point where the two equal sides intersect down to a right angle with the base) then use the following equation.(side*arcsin(your angle)*(side*arccos(your angle))

How do get the size of exterior angle giving eight sides?
If we refer to your 8 sided shape as a regular octagon we can use the formula 360/n to work out the side of a single exterior angle. n refers to the number of sides. In this case the equation you would use would be 360/8 which in turn equals 45 degrees. So the size of a single exterior angle in a octagon is 45 degrees.
How do you convert j equations to phase angle equation?
The phase angle is the angle that has a tangent of (imaginary part)/(real part).
What is the supplementary angle of 91.4?
When finding a supplementary angle, you can simply use a + b = c. C will always equal 180. In this case A is 91.4. So your equation is:91.4 + B = 180180 - 91.4 = BB = 88.6.The supplementary angle is 88.6.

Equation on how to find no of sides using interior angle 120?
(360) / (180 - n) n= interior angle in this case it will work like this: 360/(180-120) 360/(60) 6, so the number of sides is six.
What is the condition for a force to do work?
The equation of work is: Work = Fd * cos o As long as theta ^, the angle between the applied force, F, and the displacement, d, has value other than 90 degrees, or pi/2 (radians), then the force will do work.
How the carpenters architects and the engineers use angles in their work and apply it by drawing?
it is use to measure angle in their house or etc.
