Let the angles be A B C and their opposite sides be a b c and by using trigonometry in the form of the cosine rule the 3rd side works out as 7.97 cm and the other angles are 42.65 degrees and 65.12 degrees.
How do you solve for y square root of 2 x minus 1?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.
Here, it is not clear whether the question is about y = sqrt(2x - 1) or y = sqrt(2x) - 1. The solutions in the two cases are different.
A key part of plumbing is installing piping with the proper slopes for drainage. That requires a good understanding of angles and triangles.
Where does the word fight come from?
it comes from an Old English word 'Lyftgelac' meaning flight through the air. The word 'to flee' in Old English is 'Aetfleon'
How do you draw the Arctic Circle?
The Arctic Circle is an imaginary line on globes and charts at about 66.5°N latitude. Locations north of the Arctic Circle can experience at least one 24-hour period of "night" during the winter. At the North Pole, this becomes 6 months of daylight and 6 months of night.
To "draw" the Arctic Circle, make a circle centered on the North Pole, about 2600 kilometers (1616 miles) in radius.

How do you make a model for maths?
be more precise. what in maths. area or length or like pi or something. make it with clay its the easiest or make a diagram with paper.
What is the memory devise to remember the order of the trigonometric ratios?
One that is popular in the UK is
SOH - CAH - TOA
Sine = Opposite/Hypotenuse and so on.
You are meant to remember it as rhyming with "soccer tour". I don't find the latter part particularly convincing, though.
Is 2 cot x sin x cos x equals 2 2 sin 2 x an identity?
No.
But that could be because of limitations of the browser used by Answers.com. This means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".
What is the square root of negative 2 the square root of 3 squared plus negative 2 squared?
sq rt (-2) + (sq rt 3))2 + (-2)2
= i(sq rt 2) + 7 = 7 + i(sq rt 2) answer
this is a complex number, it cannot be further simplified.
Were does the word injustice come from?
In is an English prefix meaning "not". The word Justice comes from the Roman empiror Justinian who created a code of laws which systemized a legal system and created universal punishments for certain crimes.
How do the roles of government affect your day-to-day life?

What are the attributes of a cosine function?
There are many "attributes" of a cosine function. Some examples of attributes are as follows:
For, constants a, b, n,
y=a*cos(nx)+b has an amplitude of a, a period of 2pi/n, a range of [-a+b,a+b], a derivative of y'=-an*sin(nx).
Using Pythagoras' theorem it is 20 feet
How do you find the perimeter of a triangle when two angles are given And one is a 90 degree angle?
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
Somehow I messed up andused 31 instead of 35

Do a Google search for Diagonal of a cube
Find this website.
mathcentral.uregina.ca/QQ/database/QQ.09.04/brett1.HTML - Draw a cube
You will see how to find the diagonal of a cube.
You use Pythagorean Theorem
Draw a cube
Label each side as s
Draw the diagonal of the base of the cube
Diagonal of base = (s^2 + s^2 )^0.5
Let the diagonal of the base be the horizontal side of the right triangle whose hypotenuse is the diagonal of the cube.
The height of the cube is the vertical side of the right triangle whose hypotenuse is the diagonal of the cube.
Now determine the length of the diagonal of the cube.
(diagonal of base)^2 + (height of cube)^2 = (diagonal of cube )^2
Diagonal of base = (s^2 + s^2 )^0.5….Height of cube = s
Use Pythagorean Theorem
(diagonal of cube )^2 = (diagonal of base)^2 + (height of cube)^2
(diagonal of base)^2 = [(s^2 + s^2 )^0.5]^2 = s^2 + s^2
height of cube)^2 = s^2
(diagonal of cube)^2 = (s^2 + s^2 + s^2)
(diagonal of cube )^2 = (3 * s^2)
diagonal of cube = (3 * s^2)^0.5 = 35
(3 * s^2)^0.5 = 35
Square both sides
3s^2 = 31^2 = 1225
s^2 = 408.33
s = 40833^0.5
s = 20.2 cm
How many vertices or corners in a cube?
- 8 vertices (or corners)
- 6 faces,
- 12 edges
Cube means a 3 dimensional figure. Its faces are in square shape. Cube has 6 square faces, attached by one edge of a square with another edge of another square . Two types of cubes are there one is solid cube and other is hollow cube. If three square faces come in contact with one another by their edges then we get a corner or vertex. So, the number of corners or vertices are 8.
A cube has 8 vertices, 12 edges and 6 faces
How do you convert meters per second squared to feet per second squared?
To convert meters to feet, multiply by 3.281. It does not matter about the "per second squared" since that is present in both sides.
Why did that he was the father of algebra?
If you really want to get an answer, ask a better question. I can't even tell what you are asking.
Using trigonometry its perimeter rounds up to 14 cm and its area rounds up to 8 square cm
