Changing the screen orientation of your Windows display can make your screen rotate at a 90-degree, 180-degree and 270-degree angle. By default, Windows operating systems do not come with a built-in mechanism to change the screen's orientation. Certain graphics boards, such as Intel, utilize hot keys to change the screen orientation. If the hot keys do not work on your computer, a program can be installed to create shortcuts that change the screen's orientation. One such program that is Windows compatible is called "iRotate," which is available to download for free.

Turn your computer on and wait for it to load. Once your computer finishes loading, make sure any open programs are minimized or closed. Press and hold the "Ctrl" and "Alt" keys on your keyboard. Press the corresponding arrow key on your keyboard for the direction to which you want to orient your screen. Press and hold the "Ctrl," "Alt" and up directional arrow key to return the screen to its regular orientation. iRotate Application Open the iRotate download site (see Bottom of page.) in your web browser. Click on the blue download link on the left-hand side of the page. The download link contains the text "iRotate" and has an icon of a floppy disc. Save the file to your computer. Open the iRotate file and follow the on-screen prompts to install the program to your computer. You can choose whether or not to put a shortcut on your desktop, place a folder for the program in your "Start" menu or automatically run the program after it finishes installing itself. Right-click on the iRotate icon in your taskbar. The iRotate icon is a blue rectangle that will display information about your graphic properties when you hover your mouse over the icon. Select a screen orientation from the drop-down menu. You can choose a 90-degree, 180-degree or 270-degree rotation. The "Normal Landscape" option returns your screen to its default orientation. iRotate

Well, there is classification by sides, equilateral with 3 equal sides, Isosceles with two equal sides, and scalene with no equal sides, but you talk about angles, but I wanted to point out equilaterals have 3 equal angles, isoceles have 2 equal angles and scalene have no equal angles.
So, now we talk about angles: a Right trianlge has one angle that is 90 degrees, an Obtuse triangle has one angle greater than 90 degrees, and an Acute has no angles over 90 degrees.
Thus, it is possible to have a (scalene or isoceles) AND (acute, obtuse, or right) triangle, but never an equilateral AND (obtuse or right). The angles can't be equal and 90+ degrees if all three must equal 180 degrees.

It is called as keystone distortion. To correct the problem press the "Keystone" button on the projector, then press left, right, down & up arrow buttons to adjust the angle at 90 degrees.

You can add angle measures by hitting 2nd angle and choosing the degree option. Put this after a value (e.g. 90(degrees symbol)) and add you can add angles that way. Be sure that you are in degree mode when doing this (you can use the radian symbol for adding radians too). Still, this is a very tedious process and I recommend just adding angles as regular values (e.g. 90 + 200 = 290) and correcting for degrees manually.

The cutter is put on at a 90 degree angle and then turned 90 degrees into place

Hello this is Baris,
First off all when you say hypotinuse I think it is a 90 Degree triangle. Total of the angles off a triangle is 180 degree. So it is a simple algebra question.

Hypotinuse is 90
Right angle is R
Left angle is L
Total is 180

Equation is 90+ R +L = 180

We are looking for R, so lets arrange our equation.

R= 180 - 90 - L
R= 90 - L

This is our formula for excel

Lets put it in the excel
Type in A1 "hypotinuse "
Type in A2 "Left Angle"
Type in A3 "Right Angle"

Type in B1 90
Type in B2 "whatever the value given for the left angle"
Type in B3 =90-B2

As soon as you change the value in the cell B2, B3 will change by itself. Hope this helps :)

might try

(54tan)/45

I don't have a calc that will do it or I would try it and see.
