Just the 1 (corresponding to the tallest bar between 45.0 and 52.5 on the horizontal axis)
In order for a regular polygon to tile a plane, the interior angle must be a divisor of 360°. The interior angle at each vertex will have measure 180(n -2)/n for an n-sided polygon. So you must have
.. 360/(180(n -2)/n) is an integer
.. = 360n/(180(n -2))
.. = 2 +4/(n -2)
That is, n-2 must be a divisor of 4, one of 1, 2, 4. So, the number of sides of the regular polygon must be 3, 4, 6.
Of your choices, A and D are appropriate.
Answer: .679
Step-by-step explanation:
move the decimal to the left two places.
2.5 belongs woth numbers under 10 and decimals
You simply divide, since it's a fraction. If you divide 14 b7 25, you get an answer of 0.56. :)
