Marina wants to install security cameras in her store, which has dimensions 48 feet by 48 feet. each camera can view an area of approximately 128 ft2, with a viewing area shaped like a right triangle.

the distance between grid lines is 4 feet.

how many cameras will be necessary to cover the entire store?

18 cameras will be necessary to cover the entire store.

Step-by-step explanation:

Length of the store= l = 48 feet

Width of the store = w = 48 feet

Area of the store , A= l × w =

Area covered by single camera , a=

Let the n number of cameras are required to cover the store .

18 cameras will be necessary to cover the entire store.

im sorry but no. i just need to answer for 50 poonts oof

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
