I might be wrong but I’d say the answer is B). Tim must work at least 6 hrs....
I say this cuz the open circle in an equation and on the graph line represents less than/more than or equal too. In this case (on a graph) it means more than or equal too so letter b makes more sense to me
Answer: ![x=10.2](https://tex.z-dn.net/?f=x%3D10.2)
Step-by-step explanation:
The triangle shown in the image attached is a right triangle.
Therefore, you can calculate the value of <em>x</em> as you can see below:
![cos\alpha=\frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cos%5Calpha%3D%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
In this case, you have that:
<em> adjacent=x</em>
<em> hypotenuse=11</em>
![\alpha=22\°](https://tex.z-dn.net/?f=%5Calpha%3D22%5C%C2%B0)
Therefore, when you substitute values and solve for <em>x</em>, you obtain the following result:
![cos(22\°)=\frac{x}{11}\\\\x=11*cos(22\°)\\x=10.2](https://tex.z-dn.net/?f=cos%2822%5C%C2%B0%29%3D%5Cfrac%7Bx%7D%7B11%7D%5C%5C%5C%5Cx%3D11%2Acos%2822%5C%C2%B0%29%5C%5Cx%3D10.2)
Answer:
they are similar
Step-by-step explanation:
1.6/1.2=1.3333
2.8/2.1=1.3333
they are similar as their ratios of the legs are equal
