B/c if u cut it in half.....................




All 30-60-90-degree triangles have sides with the same basic ratio. If you look at the 30–60–90-degree triangle in radians, it translates to the following:
30, 60, and 90 degrees expressed in radians.
In any 30-60-90 triangle, you see the following:
  • The shortest leg is across from the 30-degree angle.
  • The length of the hypotenuse is always two times the length of the shortest leg.
  • You can find the long leg by multiplying the short leg by the square root of 3.
Note: The hypotenuse is the longest side in a right triangle, which is different from the long leg. The long leg is the leg opposite the 60-degree angle.
The figure illustrates the ratio of the sides for the 30-60-90-degree triangle.

A 30-60-90-degree right triangle.
A 30-60-90-degree right triangle.
If you know one side of a 30-60-90 triangle, you can find the other two by using shortcuts. Here are the three situations you come across when doing these calculations:

From wiki..........about a Tom Clancy novel................. Simultaneously, the Soviets seize  Iceland  in a covert surprise attack with the Soviet merchant ship  Julius Fucik  disguised as a  Lykes Lines  American  LASH ship , capturing the NATO air station at  Keflavík  and eliminating the  GIUK - SOSUS  line to allow the  Soviet Navy  to surge its submarines into the Atlantic Ocean without being detected. In addition, the Soviet Navy takes steps to protect its  ballistic missile submarine  fleet in coastal waters behind minefields and ASW assets, freeing up its attack submarines to engage and destroy NATO shipping. Thus, the Soviet Navy is able to act as an offensive weapon contrary to pre-war NATO expectations, becoming a major strategic threat against  resupply convoys coming from North America  with both aircraft and submarines. This advantage is put to immediate use as a NATO carrier battle ...
