You can calculate polygon area with only apothem OR side length.
apothem only
area = apothem^2 * 6 * tan (180/6)
area = 10.4^2 * 6 * 0.57735
area = 108.16 *

<span>
<span>
3.4641
</span>
</span>
</span>
area =
<span>
<span>
<span>
374.677056
</span>
</span>
</span>
square yards
side length only
area = 6 * 12^2 * / 4*tan(30)
area = 864 / 4 * 0.57735
area = 864 /

area =

If apothem and side length were given with more precision, the answers would be closer.

The angular quantum number

can be any integer (whole number) between 0 and one less than the principal quantum number

.

cannot be -3, -2, or -1. The other solutions depending on what the principal quantum number is.
The same shape and size. Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other. ... Angles are congruentwhen they are the same size (in degrees or radians). Sides arecongruent when they are the same length. Congruent.
The correct answe would be C...
