Answer 1

Answer:

Happy new year in advance

Answer 2

Given:

Height of the laptop screen = 10 inches

Width of laptop screen = 24 inches

To find:

The diagonal length of the laptop screen.

Solution:

Since the laptop screen is a rectangle, the angle between each sides will be 90° hence we can use the Pythagoras Theorem:

Let the length of the diagonal be d:

d² = (width of screen)² + (height of screen)²

d² = 24² + 10²

d² = 576 + 100

d² = 676

Taking under root on both sides:

d = 26

Therefore the length of the diagonal of the laptop screen will be 26 inches.
