<h2>Right answer: It is used to measure long distances in space</h2>
A light year (
) is a distance unit that is approximately 
.
By definition it is <em>the distance that a photon would travel in vacuum during a Julian year (365.25 days) at the speed of light (299 792 458 m/s) at an infinite distance from any gravitational field or field magnetic.
</em>
<em>
</em>
In other words:
It is the distance that light can travel in a year.
This unit is used to measure large distances in space. Therefore the correct answer is D.
The things an ocean engineer is to consider in building a fish tank for a salt water fishery list are:
- The Water supply
- The Water quality.
- The Climate.
- The Hydrological characteristics.
- The Soil characteristics.
- The Land.
<h3>What are the basic element for fish farming?</h3>
They are:
- Land
- Water
- Capital
- Market
- Management skills
Before the ocean engineer will build, he will need to consider or look into these requirements as it is one that will help them to be able to plan and create the fish tank.
Note also that Ocean engineers are people who are said to be involved in the act of designing, building, testing of different kinds of tools or equipment and as such the things an ocean engineer is to consider in building a fish tank for a salt water fishery list are:
- The Water supply
- The Water quality.
- The Climate.
- The Hydrological characteristics.
- The Soil characteristics.
- The Land.

um is this some kind of sequence?
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.
