Step-by-step explanation:
Simplify the exponents and then multiply
Multiply the dimensions by 3 to convert to feet.
12 x 3 = 36 ft.
15 x 3 = 45 ft.
the dimensions are 36 ft. x 45 ft.
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
The answer is 15 because I checked it with Socratic
