Question

The screen on Jeff's computer monitor has a length of 15.2 and a width of 11.5 in. How do you find the measure of the diagonal for Jeff's monitor?

Answer 1

`19.06` to 2 decimal places

Explanation:

This forms a right triangle so you can use Pythagoras.

Let the diagonal be `d` then we have

`d^2=(15.2)^2+(11.5)^2`

`d=sqrt(231.04+132.25)`

`d=19.06` 2 decimal places
