Question

*What is the diagonal length of a TV screen whose dimensions are 80 x 60 cm?*

1️⃣ 10 cm
2️⃣ 100 cm
3️⃣ 20 cm
4️⃣ 1000 cm​

Answer 1

Answer:

2.100cm

Explanation:

So, Applying Pythagoras Theorem,

$( {diagonal)}^{2} = {80}^{2} + {60}^{2} = 6400 + 3600 = 10000 \\ diagonal = 100cm$

Answer 2

$\huge\underline \mathfrak\orange{Answer}$

$2). 100$

$\mathcal{Let's \: see \: how \: :- \: }$

For this question we can apply Pythagoras theoram

let's assume the TV as ABCD and let $AB = 80 cm$ and $BC = 60 cm$

now draw a diagonal $AC$

now $ABC$ is a triangle

so $AC² = AB² + BC²$

$AC² = 80² + 60²$

$AC² = 6400 + 3600$

$AC² = 10000$

so $AC = 100 cm$

So the correct answer is $2). 100$
