Trigonometry

A three-sided figure with two equal sides is called an isosceles triangle. In an isosceles triangle, two sides are of equal length, while the third side may be a different length. The angles opposite the equal sides are also equal in measure. Isosceles triangles exhibit unique properties in geometry, such as having a line of symmetry along the axis of the unequal side.

In the third quadrant, both the x and y coordinates are negative. Since tangent is defined as the ratio of the opposite side to the adjacent side in a right triangle, in the third quadrant where both sides are negative, the tangent of an angle theta will be positive. Therefore, tan theta is not negative in the third quadrant.

Well, let's turn that decimal into a mixed number, shall we? 1.99 is the same as 1 whole and 99 hundredths. So, our mixed number is 1 99/100. Just a happy little conversion to brighten up your day!

Oh, dude, another name for a square-based pyramid is a "pyramid with a square base." Like, it's literally in the name. It's not rocket science, just a pyramid chillin' on a square. So, yeah, square-based pyramid, that's the vibe.

To perform matrix calculations on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Press the "Mode" button, then select "Matrix" mode by pressing the corresponding number key. Next, input the dimensions of the matrix (rows and columns) and enter the values of the matrix. Once the matrix is entered, you can perform operations such as addition, subtraction, multiplication, and finding the determinant or inverse using the matrix menu options.

To solve the equation 2cos(x) + cos(x) - 1 = 0, we first combine like terms to get 3cos(x) - 1 = 0. Then, we isolate the cosine term by adding 1 to both sides to get 3cos(x) = 1. Finally, we divide by 3 to solve for cos(x), which gives cos(x) = 1/3. Therefore, x = arccos(1/3) or approximately 70.53 degrees.

In mathematics, symmetry refers to a property where an object remains unchanged when it undergoes a transformation. For a number to be symmetrical, it must read the same forwards and backwards. For example, the number 121 is symmetrical because it reads the same forwards and backwards. However, the number 123 is not symmetrical as it reads differently when reversed.

15*cos(60) = 7.5

Oh, dude, let me break it down for you. So, we've got this quadrilateral ABCD with all these angles, right? And we need to find angle AEB, where E is the intersection point of AC and BD. Like, just do a little math magic with those angles, and you'll see that angle AEB is 80 degrees. Easy peasy, lemon squeezy!

A tetragon (a polygon with four sides) is more commonly known as a quadrilateral.

Do you mean

Sin(pi/7) or {Sin(pi)} / 7

Note the position of the '7' be it inside or outside the Sine Function.

Clarity is needed, in the position of the '7'.

However,

Maker sure you calculator is in 'Radian' mode.

Sin(pi/7) =

Sin(0.44879895...)

=0.0078329....

or

{Sin(pi)}/7 = 0.054803665.../7

= 0.007829095021....

Note the two different answers.

Theta is the classical Greek letter. It looks like an 'O', with an horizontal line through it.

It is used as an angular symbol in Trigonometry.

e.g.

Sin (Theta) = 0.5

So inverting Theta = 30 degrees.

Pythagoras.

The right turn is assumed to be 90 degrees, and moving southwards.

This forms the two shorter sides on a right angled triangle.

They applying Pythagoras.

h^)2) = 5^(2) + 12^(2)

h^(2) = 25 + 144

h^(2) = 169

Don't forget to 'square root' both sides!!!!

Hence

h = sqrt(169) = 13 .

This is a classic Pythagorean triangle.

'Axes'.

Linear ; x- axis

2- dimensional ; x-axis and y-axid.

3-dimensional ; x-axis, y-axis, and z-axis.

For all triangles, right-angled included, it is the multiplication of the base length times the perpendicular height x half.

Algebraically

A = 0.5bh

For a right-angled triangle it is the base length times to length of right angled (perpendicular) line times one half.

the origin and it has the coordinates of (0,0)

In geometry (math) a 3 -sided linear figure is called a triangle. The lines connect and the resulting angles always equal to a total of 180º. There are 3 types of triangles and this is one:

If you type the word "triangle" into your browser or http://answers.com search box you will get detailed information and some information about more triangles. GOOD LUCK !!!

-3 + ln x = 5

Add '3' to boths sides

Hence ln x = 8

'ln' is logarithms to the natural base , which is 2.718281.... = 'e'

Hence log(e) x = 8

x = e^(8)

x = 2.71828...^8) = 2980.95798...

NB One the calculator you will find two buttons, viz. 'log' & 'ln'.

Log is logarithsm to base '10'

Ln is logarithms to base 'e' = 2.71828.... ( The exponential .

A 3d shape with 5 faces can be a square pyramid

Each bars height represents a certain number. Read all these heights and add the numbers together. Then take each individual bars value divide that by the total and multiply by 100 to get percentages.

Oh, dude, it's like asking the difference between a hot dog and a hamburger. So, like, the main difference is just a phase shift of 90 degrees. Sine starts at zero, cos starts at one, but they're basically like two sides of the same math coin.

Coordinate planes are typically labeled with Roman numerals to distinguish between the horizontal axis (X-axis) and the vertical axis (Y-axis). Roman numerals are used as a traditional and standardized way to label the axes in mathematics to avoid confusion. This labeling convention helps to clearly identify the axes and their corresponding values when graphing points or plotting equations on the coordinate plane.

Well, darling, you've got yourself a right triangle situation here. Using some good ol' trigonometry, you can solve for the height of the tower. The tangent of 75 degrees is equal to the height of the tower divided by the distance from the base to the point where the guy wire touches the ground. So, the height of the tower is approximately 209 feet. Voilà!

Oh, dude, you're hitting me with some math lingo there! So, if x is acute and cos x is 0.6, we can use the Pythagorean identity to find sin x, which is 0.8. Then, to find tan x, we just divide sin x by cos x, giving us 0.8 / 0.6, which simplifies to 4/3. So, tan x is 4/3. Math can be cool, but like, let's not get too serious about it, right?

Well, darling, the value of tan(58.5 degrees) is approximately 1.612. So, if you're looking to impress someone with your trigonometry skills, go ahead and drop that little nugget of knowledge on them. Just don't expect them to be as impressed as they should be.
