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. .
