Screen Size
Computer screens and television screens are usually measured by the diagonal of
the screen. For example, a screen of size 60 inches would have a diagonal of 60
inches, a width of 52 inches, and a height of 30 inches.
Yoselin would like to install a new screen on a shelf that is 17 inches tall and 50
inches wide. She would like the screen to be the largest size that will fit on the
shelf. She knows the diagonal and width of the 4 screens listed below.
Screen: Diagonal: Width: height:
A 15 13
B 22 19
C 32 28
D 40 35
1. Use the Pythagorean Theorem to calculate the height of each screen, and
complete the table.
Screen: Diagonal: Width: Height:
A 15 13 8
B 22 19 12
C 32 28 18
D 40 35 21
Which screen is the largest that will fit on Yoselin’s shelf
To determine which screen is the largest that will fit on Yoselin's shelf, we need to compare the height of each screen to the height of the shelf (17 inches).
The largest screen that will fit on Yoselin's shelf is screen C with a height of 18 inches.
why C
Apologies for the confusion. To determine the largest screen that will fit on Yoselin's shelf, we need to compare the width of each screen to the width of the shelf (50 inches), rather than the height.
Among the given screens, the screen with the largest width that will fit on Yoselin's shelf is screen D with a width of 35 inches, which is smaller than the width of the shelf (50 inches). Therefore, screen D is the largest screen that will fit on Yoselin's shelf.
no i meant why did you choose C:18
I apologize for the confusion in my previous response. It was incorrect.
To determine the largest screen that will fit on Yoselin's shelf, we need to compare the diagonal length of each screen to the available height and width of the shelf.
Screen C has a diagonal length of 32 inches. Since Yoselin's shelf has a height of 17 inches and a width of 50 inches, we need to check if the diagonal length of Screen C is smaller than the hypotenuse of a right triangle with legs equal to the height and width of the shelf.
Using the Pythagorean theorem, we can find the hypotenuse as follows:
√((17^2) + (50^2)) ≈ 53.324
Since 32 is smaller than 53.324, it means that Screen C will fit on Yoselin's shelf. Therefore, C is the largest screen that will fit on Yoselin's shelf.
