You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
Answer:
c
Step-by-step explanation:
=16
![\sqrt[3]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B16%7D)
8/10 if simplified 4/5 idk how to explain it tho lol
We can always split a regular polygon with
sides into
triangles, whose base is the side of the polygon and whose height is the apothem of the polygon. So, the sum of the areas of all these triangles is

where
is the number of sides,
is the side length, and
is the apothem length.
So, you just need to plug you values in: in your case, you have 
So, the formula becomes

A is not congruent
B is not congruent
C is congruent
D is not congruent
E is congruent
Is congruent
