What is the use of the half angle formula in real life?
The half angle formula is used to calculate chord length in circles. This is particularly helpful in complex construction projects involving curves. It's not like you'll be doing this if you're in marketing, selling insurance, or are holding down the sous-chef de cuisine slot at a five star hotel. But it's real enough to those who work with this in engineering.
What is the angle measure or degree for one half?
180 degrees, if you mean a half circle
What shape has two parallel sides two pairs of equal angle and half of it are obtuse angle?
a parelelogram
What are two angles you would get if you spilt a right angle in half?
A right angle is 90 degrees. If you split it in half perfectly, each resulant angle would then be 45 degrees. (90/2). Source- 12 years of math.
How does one get the formula for an equilateral triangle?
the formula for the area of equilateral triangle with side length a is (a^2)(sqrt(3)/4 ) So draw an equilateral triangle with sides a,a,a. Now divide it into two triangles by bisecting the top angle and extending that line down so it makes a 90 angle with the base. (any angle will do since it is symmetric, but I am trying to help you draw it) Now the new half triangle you have is a 30 60 90 triangle since the top angle is half the original which was 60 and the lower left angle is still 60. The 90 degree angle is the third angle and we are drawing it this way so we have a that the side between the 30 and 90 degree angles is the height of the triangle and we can use 1/bh which is the area formula. The new base has length a and the height is sqrt3(a) because it is a 30-60-90 triangle so 1/2 bxh= 1/2(1/2 )a (sqrt3)a=(1/4)a^2( sqrt3 )since 1/2 base = a/4 and height is sqrt3 x a
What is the half angle formula to find the exact value for tan 165?
tan u/2 = sin u/1+cos u
What is the half angle exact value for Tan 165?
tan 165/2 = 1.068691
What is the half angle formula?
The half angle formula is: sin theta/2 = ± sqrt (1 - cos theta/2)
How can half angle identities help solve nonspecial angle measures?
15 degrees is not a special angle, but it is half of 30, which is a special angle. If you need sin 15 you can use the half angle formula with 30 degrees.
What is the exact value of cos 120?
negative one half
How do you use a trigonometric chart with the angle of 80 degrees?
you could use 160 degrees which will be in the tables and use the half angle formula
How many GB in 600000 kilobytes?
That is about a half of I gigabyte. The exact value is 0.5722GB.
What is the minimum deviation of prism whose refractive index is three to the power half?
The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
Does a bisector cut an angle in half?
To bisect an angle is to divide the angle in half.
Jack tosses a coin thirty times how many times would you expect the coin to land tails side up?
About 15 times - half of 30. This will not necessarily be the exact value; just the long-term average if you do the experiment many, many times.About 15 times - half of 30.

What is the measurement of an angle that is half as large as the other angle?
The first angle that is half as large as the other angle is 30º The other angle that is the larger is 60º
One half of a right angle turn?
One half of a right angle is a 45 degree angle.
