Answer:
3.23
Step-by-step explanation:
8 pigs x 4 legs each = 32. so you need 2 ducks to give you 10 animals total. So 32 + 2 ducks with 2 legs = 36.
There are 8 pigs and 2 ducks.
X=7/2 which is equal to 3.5
Answer:
10.5 in
Step-by-step explanation:
Given
![tan(55) = \frac{15}{b}](https://tex.z-dn.net/?f=tan%2855%29%20%3D%20%5Cfrac%7B15%7D%7Bb%7D)

Find length AC
The question is not detailed enough; so, I'll assume that b represents line AC.
Having said that;
We start by multiplying both sides by b
![tan(55) = \frac{15}{b}](https://tex.z-dn.net/?f=tan%2855%29%20%3D%20%5Cfrac%7B15%7D%7Bb%7D)
![b * tan(55) = \frac{15}{b} * b](https://tex.z-dn.net/?f=b%20%2A%20tan%2855%29%20%3D%20%5Cfrac%7B15%7D%7Bb%7D%20%2A%20b)
![b * tan(55) =15](https://tex.z-dn.net/?f=b%20%2A%20tan%2855%29%20%3D15)
Divide both sides by tan(55)
![\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%20%2A%20tan%2855%29%7D%7Btan%2855%29%7D%20%3D%20%5Cfrac%7B15%7D%7Btan%2855%29%7D)
![b = \frac{15}{tan(55)}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B15%7D%7Btan%2855%29%7D)
Find tan(55)
![b = \frac{15}{1.42814800674}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B15%7D%7B1.42814800674%7D)
![b = 10.5031130731](https://tex.z-dn.net/?f=b%20%3D%2010.5031130731)
