Question

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?

Answer 1

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.

$d^{2} = h^{2} + w^{2}$

$h^{2} = d^{2} - w^{2}$

Solution:

$h^{2} = d^{2} - w^{2}$

$h^{2} = 34^{2} -30 ^{2}$

$h^{2} = 1156 -900$

$h^{2} = 256$

$h = \sqrt{256}$

h = 16 inches

Hence TV is 16 inches tall.
