Answer:Because it has a variable along with Addition
Step-by-step explanation:
Answer:
The recent role of the greenhouse effect
Step-by-step explanation:
Let the width be x, then the length is x + 10.
Area = length x width = x(x + 10) = 200
![x^{2} +10x = 200](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B10x%20%3D%20200)
Solving the quadratic equation, we have that
x = 10 feet
i.e. the width is 10 feet.
Answer:
and ![tan\theta =\pm \frac{5}{\sqrt{11} }](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%5Cpm%20%5Cfrac%7B5%7D%7B%5Csqrt%7B11%7D%20%7D)
Step-by-step explanation:
Since, here ![sin\theta=5/6](https://tex.z-dn.net/?f=sin%5Ctheta%3D5%2F6)
And we know that ![cos\theta =\sqrt{1-sin^2\theta}](https://tex.z-dn.net/?f=cos%5Ctheta%20%3D%5Csqrt%7B1-sin%5E2%5Ctheta%7D)
So ![cos\theta=\sqrt{1-(5/6)^2} =\sqrt{1-25/36} =\sqrt{11/36} =\pm\frac{\sqrt{11} }{6}](https://tex.z-dn.net/?f=cos%5Ctheta%3D%5Csqrt%7B1-%285%2F6%29%5E2%7D%20%3D%5Csqrt%7B1-25%2F36%7D%20%3D%5Csqrt%7B11%2F36%7D%20%3D%5Cpm%5Cfrac%7B%5Csqrt%7B11%7D%20%7D%7B6%7D)
Thus, ![cos\theta=\pm\frac{\sqrt{11} }{6}](https://tex.z-dn.net/?f=cos%5Ctheta%3D%5Cpm%5Cfrac%7B%5Csqrt%7B11%7D%20%7D%7B6%7D)
Now, we know that
Thus, ![tan\theta=\frac{5}{\pm \sqrt{11} }](https://tex.z-dn.net/?f=tan%5Ctheta%3D%5Cfrac%7B5%7D%7B%5Cpm%20%5Csqrt%7B11%7D%20%7D)
