Question

. Which size would you see on the box for a new television whose screen measures 27inches wide by 15 inches high?

Answer 1

Screens are a measure of the diagonal of the box. As you can notice in the following image:

The hypotenuse h determines the size of the screen. Use the Pythagoras theorem to find the value of h, as follow:

`\begin{gathered} h^2=(15)^2+(27)^2 \\ h^2=954 \\ h=\sqrt[]{954}\approx30.98 \end{gathered}`

Hence, the size of the screen would be approximately 30.98 inches
