Question

PLZ HELP ASAP WILL MARK U BRANLYEST... thanks:)

Answer 1

Explanation:

Here we are going to use the Pythagoras theorem to get the Hight of the Television

`{42}^(2) - {32}^(2) = x`

X Being the unknown side

`{42}^(2) - {32}^(2) = 740 \\ x = √(740) = 27.2`

So the height is 27.2in

The Are of the screen would be L x B

27.2 x 32 = 870.2 in^2

We will use Pythagoras for the last question also

`{40}^(2) + {32}^(2) = 2624 \\ √(2624) = 51.23`

She will need 51.23 in screen size
