Answer: Mural height: 22ft and the Mural width is 10ft
Step-by-step explanation: I took the test and got it wrong, but they told me the correct answers after I took the test. (I got to K-12) Proof:
The number in the photo should be the answer but the problem might just be that your question was worded incorrectly.
Answer: 23 + 9 = 32
Step-by-step explanation:
Answer:
1. 30
2. 150
Step-by-step explanation:
![3tan^2(x)-1 =0](https://tex.z-dn.net/?f=3tan%5E2%28x%29-1%20%3D0)
Lets assume tan(x) = u
![3u^2(x)-1 =0](https://tex.z-dn.net/?f=3u%5E2%28x%29-1%20%3D0)
Now we solve for 'u'
add 1 on both sides
, divide both sides by 3
![u^2 = \frac{1}{3}](https://tex.z-dn.net/?f=u%5E2%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
Take square root on both sides
![u = +-\frac{1}{\sqrt{3} }](https://tex.z-dn.net/?f=u%20%3D%20%2B-%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%20%7D)
We replace tan(x) for 'u'
x = 30 because
in first quadrant
x = 30 (tan is positive in first quadrant)
x = 150 because
in second quadrant
tan is negative in second quadrant
