Mrs. Martina wants to put a wire fence around her garden which is 12 feet long and 6 feet wide. How much fencing does she need?
1 answer:
The cost for her to purchase the fence is $108.
<h3>How to calculate the cost?</h3>
Since she wants to put a wire fence around her garden which is 12 feet long and 6 feet wide, the total perimeter will be:
= 2(length + width)
= 2(12 + 6)
= 36 feet
Therefore, the cost will be:
= Total feet × Amount
= 36 × $3
= $108
Therefore, the cost for her to purchase the fence is $108.

Step-by-step explanation:
Reference angle =
= ?
Hypotenuse = 23
Adjacent side = 20
Thus, applying CAH:
![Cos(/theta) = \frac{adj}{hyp}](https://tex.z-dn.net/?f=%20Cos%28%2Ftheta%29%20%3D%20%5Cfrac%7Badj%7D%7Bhyp%7D%20)
![Cos(/theta) = \frac{20}{23}](https://tex.z-dn.net/?f=%20Cos%28%2Ftheta%29%20%3D%20%5Cfrac%7B20%7D%7B23%7D%20)
![/theta = cos^{-1}(\frac{20}{23})](https://tex.z-dn.net/?f=%20%2Ftheta%20%3D%20cos%5E%7B-1%7D%28%5Cfrac%7B20%7D%7B23%7D%29%20)
