Answer:

26.2 inches

Step-by-step explanation:

The diagonal of the TV = 60 inches while

its width = 54 inches.

The TV is a rectangle and the diagonal split it into two equal right-angled triangle, therefore

Pythagoras' Theorem is used to find the height of the TV.

[tex] {hypotenus}^{2} = {adjacent}^{2} + {opposite}^{2} [/tex]

[tex] {height}^{2} = {60}^{2} - {54}^{2} [/tex]

= (60 - 54)(60 + 54)

= (6)(114(

= 684

Take the square roots of both sides

height = √684

= 26 1534 inches

= 26.2 inches

Hence, the height of the TV is 26.2 inches
