F=94°. Angles in a quadrilateral add up to 360°,so we subtract all given angles from 360 to get 94
Answer:
The area of the regular pentagon is ![A=858.55\ in^{2}](https://tex.z-dn.net/?f=A%3D858.55%5C%20in%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of a regular polygon is equal to
![A=\frac{1}{2}Pa](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7DPa)
where
P is the perimeter of the regular polygon
a is the apothem
Find the perimeter P
----> the regular pentagon has five equal sides
---> distance from center to middle of side
substitute
![A=\frac{1}{2}(111.5)(15.4)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%28111.5%29%2815.4%29)
![A=858.55\ in^{2}](https://tex.z-dn.net/?f=A%3D858.55%5C%20in%5E%7B2%7D)
