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. .
The dimensions of the image are twice the dimensions of the preimage,
which indicates that the transformation is a dilation.
- The transformation <em>T</em> is; <u>a dilation transformation with a scale factor of 2, D₂</u>
Reasons:
The transformation applied to ΔABC = T
The image of ΔABC following the transformation, T = ΔA'B'C'
The perimeter of ΔA'B'C' = Twice the perimeter of ΔABC
Therefore, we have;
A'B' + B'C' + A'C' = 2 × (AB + BC + AC)
Which gives
A'B' + B'C' + A'C' = 2·AB + 2·BC + 2·AC
By similar triangles, we have the ratio of corresponding sides as follows;
Which gives;
A'B' = 2·AB
Therefore;
- Triangle ΔA'B'C' is twice the dimension of triangle ΔABC, and <em>T</em> is <u>a dilation transformation with a scale factor of 2, D₂</u>

After graphing the set of inequalities and looking for the overlapping of the shading, the only ordered pair that falls within this shaded area is ( -2, 2)
11 and 12
since 11*11 equals 121 and 12* 12 is 144
