Answer:
<em>Camera 2nd has to cover the maximum angle, i.e. </em>.
Step-by-step explanation:
Please have a look at the triangular park represented as a triangle with sides
a = 110 ft
b = 158 ft
c = 137 ft
1st camera is located at point C, 2nd camera at point B and 3rd camera at point A respectively.
We can use law of cosines here, to find out the angles
As per Law of cosine:
Putting the values of a,b and c to find out angles .
<em>Camera 2nd has to cover the maximum angle</em>, i.e. .
<h3>Answer: B. (-1, 0)</h3>
This point is below both the red diagonal line and the blue parabola. We know that the set of solution points is below both due to the "less than" parts of each inequality sign.
In contrast, a point like (2,2) is above the parabola which is why it is not a solution. It does not make the inequality true. So this is why we can rule choice A out.
Choice C is not a solution because (4,1) does not make true. This point is not below the red diagonal line. We can cross choice C off the list.
Choice D is similar to choice A, which is why we can rule it out as well.
