Answer:
1) 8
2) 450 ft^2
Step-by-step explanation:
Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.
The left over space in the store is the same amount of space as all the cameras space added together since each camera takes up half a square. That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the left over space, 450 ft^2.
Parallel lines have the same slope
The equation of the line is: 
The equation is given as:

The slope intercept form of an equation is:

Where:

By comparison,

The line is said to be parallel to
.
This means that the line has a slope of 
The equation of the line is then calculated as:

Where:

So, we have:

Substitute values for m, x1 and y1


Open brackets

Hence, the equation of the line is:

1. Triangular ratio
14/UV = 21/15
UV = 14/(21/15) = (14*15)/21
UV = 10 cm
