Use tangent to find the x.
tan(2) = ![\frac{100}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7Bx%7D)
![x = \frac{100}{tan(2)}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B100%7D%7Btan%282%29%7D)
Use a calculator to evaluate.
= 2863.6253
So, the boat is 2,863.63 feet from the shore.

Answer:
0.384
Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier
we need to find the chance of getting exactly one blue from 3 parakeets
![P(x=1)=nCr (p)^r(q)^{n-r}](https://tex.z-dn.net/?f=P%28x%3D1%29%3DnCr%20%28p%29%5Er%28q%29%5E%7Bn-r%7D)
n=3, r=1, p = 0.2 , q=0.8
![P(x=1)=3C1 (0.2)^1(0.8)^{2}](https://tex.z-dn.net/?f=P%28x%3D1%29%3D3C1%20%280.2%29%5E1%280.8%29%5E%7B2%7D)
