A certain television is advertised as a 17-inch TV (the diagonal length). If the width of the TV is 8 inches, how many inches tall is the TV?

15 inches

Step-by-step explanation:

We can solve this problem using the Pythagorean theorem. The formula is:

where 'c' is the hypotenuse (the longest side) and 'a' and 'b' are the legs (the other sides).

First, draw a diagram for the problem. (See the photo attached below)

We know the other leg is 8 and the hypotenuse is 17. 'a' is the missing side.

a = ?

b = 8

c = 17

Substitute the values into the equation.

Rearrange to isolate 'a'

              Square root both sides

            Square each number

            Subtract under the root

                    Find the square root

                         Final answer

Therefore, the TV is 15 inches tall.

1. 34

2. 268

3. x=14.4
