NO SPAMS

Laptop screen sizes are determined by the length of the diagonal portion of the screen, rounded to the nearest whole number. A laptop screen has a 10 inch width and the height measures 8 inches. Calculate the screen size.

Group of answer choices

12.8 inches

9 inches

6 inches

14 inches

Answer 1

Explanation:

Assuming the laptop's screen has 90° angles, you would use the pythagorean theorem.

1. X^2= A^2+B^2

2. X^2= 8^2+10^2

3. X^2= 164

4. X=Square root of 164

5. X=12.8

I am a bit confused because it says rounded to the nearest whole number so 13?

I would just put 12.8 tho
