The diagonal, height and width of the screen form a right-angled triangle, in which the hypotenuse is the diagonal of the screen, and one of the legs is the height. By the Pythagorean theorem, we can find the second leg:
√ (1002 – 602) = √ (10000 – 3600) = √6400 = 80 cm.
Answer: The width of the TV screen is 80 cm.
