A certain television is advertised as a 34-inch TV (the diagonal length). If the width of the TV is 30 inches, how many inches tall is the TV?

Respuesta :

Answer:

TV is 16 inches tall.

Step-by-step explanation:

Given Data:

Width of TV = w = 30 inches

Diagonal length of TV = d =  34 inches

To Find out:

height of TV = h = ?

Formula:

According to Pythagoras's theorem.

[tex]d^{2} = h^{2} + w^{2}[/tex]

[tex]h^{2} = d^{2} - w^{2}[/tex]

Solution:

[tex]h^{2} = d^{2} - w^{2}[/tex]

[tex]h^{2} = 34^{2} -30 ^{2}[/tex]

[tex]h^{2} = 1156 -900[/tex]

[tex]h^{2} = 256[/tex]

[tex]h = \sqrt{256}[/tex]

h = 16 inches

Hence TV is 16 inches tall.

Answer: 16
