Final answer:
The width of the screen is 8 inches.
Step-by-step explanation:
To find the width of the screen, we can set up a proportion using the given information.
Let's assign the width of the screen as 'w'. We know that the height of the screen is 8 inches and the total size of the screen is 17 inches.
Using the proportion: 8/w = 17/17, we can simplify it to w = (8*17)/17 = 8 inches. Therefore, the width of the screen is also 8 inches.
