Question

A certain television is advertised as a 10-inch TV (the diagonal length). If the width of

the TV is 6 inches, how many inches tall is the TV?

Answer 1

8 in

Explanation:

Given data

DIagonal= 10 in

Width= 6 in

`Height=???

We know that the expression that can be used to find the missing dimension is given as

d^2= w^2+h^2

substitute

10^2=6^2+h^2

100= 36+h^2

100-36= h^2

64= h^2

h= √64

h= 8 in

Hence the height is 8 in
