The size a TV screen is given by the length os it's diagonal. If the direction of a TV screen is 16 inches by 14 inches, what is the size of the TV screen
Answer:
So, the size of the TV screen is approximately 21.26 inches diagonal.
Step-by-step explanation:
To find the size of the TV screen, you can use the Pythagorean theorem since the diagonal, length and width form a right triangle.
The diagonal (D), length (L), and with (W) form a right triangle, so:
D^2=L^2+W^2
Given:
Length=16 inches
Width=14 inches
D^2=16^2+14^2
D^2=256+196
D^2=452
D=√452
D= 21.26 inches
