Quadrangle with one right angle - School Zone Shapes Preschool Full Version for PC

Assuming that the angle at A is the right angle, Pythagoras' theorem says that the length of the hypotenuse (the side opposite the right angle) is the square root of the sum of the squares of the other two sides. In your case, AB and AC are 'the other two sides' and BC is the hypotenuse, so:

/ 2 2 /
length BC = V 10 + 20 = V 100 + 400


= V 500 = 22.36 cm

(To find the angle at C, you need trigonometry and is arc-tan(10/20)

and the angle at B is arc-tan(20/10) - 26.5 deg and 63.5 deg)

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.

Let su rephrase the question, just to be sure we are on the same wavelength. The cosine of an angle is 0.5: What is the value of the angle? Right?.

First of all you must set the angle unit to degree or radian.

1. Press [SHIFT][MODE\ and select the appropriate unit.
2. Press [SHIFT][COS] to access the arc cosine function (COS^-1) enter 0.5, close the right parenthesis and hit [=]
   

If you unit is the degree you should find 60 degrees.
If the angle unit is the radian, the result should be 1.045 radian.

You need a "right angle screwdriver" or "skewdriver".

Right angle screwdrivers are kind of like tiny ratchets with screwdriver bits.

Skewdrivers are 45 degree angled screwdrivers that rotate when you twist the handle.

I prefer the craftsman right angle screwdriver, as it ratchets easily and applies more torque than a skewdriver.

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 :)

Hi rowanwah

The sine of an angle is only applicable is a right triangle. If you just want a number, ie, the actual value of the sine 15 degrees you can look it up on Google. Do a search for "sine and cosine functions"

If you want the mathematical description of the sine of an angle it is described as follows
In a triangle ABC, there are 3 angles angle A, angle B and angle C. There are also 3 sides, Side AB, Side AC and side BC. The sine of angle A is equal to the side opposite Angle A divided by the Hypotenuse (the longest side opposite the right angle)
The Cosine of angle A is equal to the side adjacent to Angle A divided by the hypotenuse

Hope this helps Loringh PS Please leave a rating for me Thanks

A friend of mine uses the same software for his PDA. I have asked him what the problem can be and he told me that some kind of “connection registry” or something like that is very important. Start PDA and start the Bluetooth. Go to Bluetooth symbol and choose BT settings. There must be shown some “magnifying glass”. Click on it and the search will start. All visible objects will be listed in the upper part of window. Mark the GPS and it will be listed in lower part of window. Click on it and start this “connection registry”. After that you can use the navigations software. Go to “GPS status” and there you must put some check mark on some green quadrangle. Sorry I can not explain you exactly what it was but I am sure that in User`s manuals of TomTom you can find a right explanation.
