Answer:
12.gon - An interior angle measures 150°
Called a Dodecagon, the sum of all of its interior angles is 1,800° therefore each individual angle is;
= 1,800/12
= 150°
15-gon - An exterior angle measures 24°
The sum of all the exterior angles of a polygon add up to 360 so a polygon with a 24° exterior angle is;
= 360/24
= 15°
16-gon - The sum of the interior angles is 2,520°
Known as a hexadecagon, each interior angle of this polygon is a 157.5° and when added up this comes to 2,520°.
18-gon - An interior angle measures 160°
The formula for calculating the interior angle of a polygon is;
Angle = (n−2) × 180° / n
160 = (n−2) × 180° / n
160n = 180n - 360
360 = 20n
n = 18
Other tiles
The sum of the exterior angles is 180º - all exterior angles must add up to 360º so this does not exist.
The sum of the interior angles is 2,160° - this is a 14 sided polygon which is not listed in the options.
When erosion from the wind pushes the grains of sand into a big pile.
Answer:
GPS makes the reading of maps very accurate.
Explanation:
An electronic version also allows the information to be upgraded regularly to give accuracy and reliability than a paper map that could be outdated. There is a less human error with machines designed to survey large areas of land. The internet is a great way to be able to access information rapidly and efficiently. Traditional maps are limited to the type of information it can show. However, with GPS mixed with GIS and the internet maps can show a great variety of information, such as the type of soil or geology in a certain area. It is also possible to read the information and connect it, such as a route planning feature to help a driver get to their destination.
