The TV size, calculated using the Pythagorean theorem, is approximately 20.01 inches.
The correct answer is option A.
To determine the TV size based on its diagonal length and height, we can use the Pythagorean theorem, as TVs are typically sized based on the diagonal. The formula is "Diagonal = square root of (Length squared + Height squared)."
For the given TV with a length of 17.1 inches and a height of 10.4 inches:
Diagonal = square root of (17.1 squared + 10.4 squared)
Diagonal = square root of (292.41 + 108.16)
Diagonal = square root of 400.57
Diagonal is approximately 20.01 inches.
Now, let's compare it with the provided options:
A) 20
B) 42
C) 55
D) 31
Option A matches the calculated size of approximately 20.01 inches. It's possible that the correct TV size might not be among the given options.
The question probable may be:
