The size of a television is given by the length of its diagonal. What is the size
MA_775_DIABLO [31]

Answer:

it is A. 60 in

Step-by-step explanation:

You need to use the Pythagorean theorem for this. Take the square root of (48^2 + 36^2). This will give you the length of the diagonal.

48^2 + 36^2 = 3600

Remember we need to take the square root of 3600, which is just 60.

The length of the diagonal is 60 inches.
