Advice 1: How to measure the angle

The angle of inclination of any line or surface can be found, knowing the trigonometric functions. Regardless of whether you calculate the angle of inclination of the roof, the back of the sofa, post or a straight line on a sheet of paper, methods of determining the angle will be the same.
How to measure the angle
You will need
  • roulette;
  • - plumb
  • - scientific calculator.
Instruction
1
To find the angle of slope, draw a right triangle, the slant line will act as the hypotenuse. To do this, use the plumb Bob, as it always creates with the ground is a right angle. Choose a starting point on your inclined plane or line, and with the help of a plumb line and measuring tape, measure the distance from that point to the earth (or any other horizontal surface such as the floor). If not plumb, just take the load and hang it on the rope. This distance is called the opposite side.
2
Then measure the distance from the point in which you rested your plummet, to the point where inclined surface rests on the ground (floor). This will be the adjacent side over. If this distance is hard to find, instead find the length of the inclined surface from the starting point to the ground (floor). It will be the hypotenuse. Anyway, in your possession should be at least two numbers are the hypotenuse and one leg or two leg.
3
If you know the length of the hypotenuse and the length of the opposite sides, calculate the sine (sin), dividing the length of the leg to the length of the hypotenuse. Now, to find the angle itself, using engineering calculator, find the inverse sine (arcsin) of the obtained number. Notice the calculator symbol may be this: sin^(-1) or asin. You will receive the angle value in degrees.
4
If you are aware of the length of the adjacent sides and the hypotenuse, find the cosine (cos), to do this, divide the length of the leg to the length of the hypotenuse. Take a calculator with a button agso (or acos or cos^-1) and calculate the inverse cosine, which is the desired angle of inclination in degrees.
5
To measure the angle of inclination at known legs, find the tangent (tg). To do this, divide the tangent to opposite adjacent. Then from that number using a calculator calculate arctg (it can also be denoted atan or tan^-1). The resulting value will be the size of the angle in degrees.
Useful advice
If you have to measure the angle of inclination often enough, purchase a special device - a protractor.

Advice 2: How to measure distance in Google

How to find out distance between point A and point on Google map? A painfully familiar question, isn't it? With the help of the map service Google is quite easy to determine the distance to a little-known town on the other side of the world or how far from your home is the nearest bus stop.
How to measure distance in Google
You will need
  • Internet access
Instruction
1
Go to Google and click on the word "Map" which is at the top of the search engine.On the right side you will see a map and the left two buttons: "Routes" and "My places". Click on "Routes". Below it will appear two Windows “A” and “b”, that is, the start and end points of reference.Let's say you are in Ufa, and you need to know how much time it will take to get to Perm. In this case the window "And" enter "Ufa" and the window "" - "Perm". Click again on the button under Windows "Routes".The map shows the route, and the Windows “A” and “b” how many miles from one city to another, and also how much time you should spend to reach by car.If you are interested in Hiking, click the button with the image of pedestrian, which is over the Windows “A” and “b”. The service will rebuild the route and automatically calculates distance and expected journey time.
2
In the case where it is necessary to measure distance from point “A” to “B”, in one locality, should act according to the above scheme. The difference lies only in the fact that the name of the area you want to add a street and possibly the house number by a comma. ( For example, “A”: Moscow, Tverskaya 5, and V: Moscow, Tsvetnoy Boulevard, 3).
3
There are times when you are interested in the distance between the objects "directly": through fields, forests and rivers. In this case, click on the icon toothed ring in the upper corner of the page. In the resulting expanded menu, select "Laboratory Google Maps" and turn on the tool to measure distances, save the changes. In the lower left corner of the map there was a line, click on it. Indicate on the map the starting point, and then endpoint. Between these points on the map a line will appear red and the panel on the left side will show the distance.
Useful advice
- you can choose one of the two units of measurement: kilometres or miles;
- clicking on several points on the map, you can determine the distance between multiple points;
- if you access the service using your profile, Google maps will remember your setup in the Laboratory of Google Maps.
