Answer: Yes, they can.
Clarification:
We have three different sides with different lengths:
These three lengths can form a triangle, an isosceles triangle.
Isosceles triangles have three different side lengths.
Hope this helps you. Best of Luck!
Answer:
10
Step-by-step explanation:
20÷2=10 because It takes two to make one.
Answer:
The answer is option 1.
Step-by-step explanation:
You have to apply Tangent Rule, tanθ = opposite/adjacent. Then, you have to substitute the following values into the formula :
![tan(θ) = \frac{oppo.}{adj.}](https://tex.z-dn.net/?f=tan%28%CE%B8%29%20%3D%20%20%5Cfrac%7Boppo.%7D%7Badj.%7D%20)
![let \: θ = 25.7 \: , \: oppo. = h \: , \: adj. = 532](https://tex.z-dn.net/?f=let%20%5C%3A%20%CE%B8%20%3D%2025.7%20%5C%3A%20%2C%20%5C%3A%20oppo.%20%3D%20h%20%5C%3A%20%2C%20%5C%3A%20adj.%20%3D%20532)
![\tan(25.7) = \frac{h}{532}](https://tex.z-dn.net/?f=%20%5Ctan%2825.7%29%20%20%3D%20%20%5Cfrac%7Bh%7D%7B532%7D%20)
![532 \tan(25.7) = h](https://tex.z-dn.net/?f=532%20%5Ctan%2825.7%29%20%20%3D%20h)
![h = 256 \: feet \: (3s.f)](https://tex.z-dn.net/?f=h%20%3D%20256%20%5C%3A%20feet%20%5C%3A%20%283s.f%29)
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
![\stackrel{f(x)}{y}~~ = ~~\cfrac{2x}{x+3}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{2y}{y+3}}\implies xy+3x=2y\implies xy-2y+3x=0 \\\\\\ xy-2y=-3x\implies \stackrel{\textit{common factoring}}{y(x-2)=-3x}\implies y=\cfrac{-3x}{x-2}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{3x}{2-x}](https://tex.z-dn.net/?f=%5Cstackrel%7Bf%28x%29%7D%7By%7D~~%20%3D%20~~%5Ccfrac%7B2x%7D%7Bx%2B3%7D%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bquick%20switcheroo%7D%7D%7Bx~~%20%3D%20~~%5Ccfrac%7B2y%7D%7By%2B3%7D%7D%5Cimplies%20xy%2B3x%3D2y%5Cimplies%20xy-2y%2B3x%3D0%20%5C%5C%5C%5C%5C%5C%20xy-2y%3D-3x%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bcommon%20factoring%7D%7D%7By%28x-2%29%3D-3x%7D%5Cimplies%20y%3D%5Ccfrac%7B-3x%7D%7Bx-2%7D%5Cimplies%20%5Cstackrel%7Bf%5E%7B-1%7D%28x%29%7D%7By%7D%3D%5Ccfrac%7B3x%7D%7B2-x%7D)
Find 33% of 185:
0.33 * 185 = 61.05
Subtract this from the regular price:
185 - 61.05 = 123.95
So the sale price is $123.95
