Question

A television is identified by the diagonal measurement of the screen. A television has a length of 57-inches and a height of 33 inches. What is the length of the diagonal of the television screen?

Answer 1

Answer: 65.86 inches

Explanation:

Length of the hypotenuse (length of diagonal) : a^2 + b^2 = c^2

The length (a)= 57

The height (b) =33

57^2= 3,249

33^3= 1,089

3,249 + 1,089 = c^2

4,338 = c^2

We next square root both sides to find c by itself (length of the diagonal)

`√(4,338) = c`

c= 65.8634952...

You can then round to however many decimals are required.

To the hundreds place: 65.86 inches
