Answer:
Regular Octagon
Step-by-step explanation:
There are only three regular shapes that tessellate – the square, the equilateral triangle, and the regular hexagon. All other regular shapes, like the regular pentagon and regular octagon, do not tessellate on their own.
Answer:

Step-by-step explanation:

First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.
-> 
Now you have
so you need a common denominator by multiplying the first fraction by 2

Then you subtract 160 - 101 which equals 59.

The Correct option is -4
because every other terms result in value = 4, where's -4 is the only different one hence doesn't belongs yo other three
5.815 equals to 5815\1000
or 
divide both sides by 2
sinΘ = - 
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ =
(
) =
related acute angle
Θ = ( π +
) = 
or Θ = ( 2π -
) =
