Answer:
Step-by-step explanation:
If 
then angle 
is in the III quadrant.
Since 
then ![x=240^{\circ}\ [180^{\circ}+60^{\circ}]](https://tex.z-dn.net/?f=x%3D240%5E%7B%5Ccirc%7D%5C%20%5B180%5E%7B%5Ccirc%7D%2B60%5E%7B%5Ccirc%7D%5D)
(we get angle in the III quadrant)
Consider 
If 
then
The surface area of the square prism is 115 square inches
<h3>surface area of a pyramid</h3>
The surface area of a pyramid is equivalent to the sum of the faces of the pyramid
For the given square pyramid;
TSA = (5*5) + 4(1/2 * 9 * 5)
Simplify to have;
Surface area =25 + 4(45/2)
Surface area = 25 + 180/2
Surface area = 25. + 90
Surface area = 115 square inches
Hence the surface area of the square prism is 115 square inches
