Answer:
a ≈ 19.45
Step-by-step explanation:
<u><em>Law of Cosines</em></u>
a=c2+b2﹣2cbcosγ
=112+132﹣2·11·13·cos(108°)
≈19.45196
5^5/5^8= 3125/390625 = 5/625 = 1/125
(1/5)^3 = 1/125
I do not believe so, because a square is in the rectangle family. If a rectangle was in the square family, it would have to have all sides the same length, wich wouldnt make it a rectangle anymore.
