Your family wants to purchase a new laptop with
zloy xaker [14]

Answer:

The laptop will not fit in the case.

Step-by-step explanation:

We need to find the width of the laptop to know if it fits in the case. We have:

<u>For the laptop</u>:

h: is the height of the laptop = 10 inch

d: is the widescreen of the laptop (diagonal) = 17 inch

w: is the width of the laptop =?

<u>For the laptop case</u>:

H: is the height of the laptop case = 10.5 inch

W: is the width of the laptop case = 13 inch

So, the width of the laptop can be found by using Pitagoras:

d^{2} = w^{2} + h^{2}

w = \sqrt{(17 inch)^{2} - (10 inch)^{2}} = 13.7 inch

Hence, the laptop is 13.7 inches wide.                              

Therefore, since the laptop is wider than the case, the laptop will not fit in the case.

 

I hope it helps you!
