Problema Solution
What does it mean to refer to a 20-in TV set or a 25-in TV set? Such units refer to the diagonal of the screen. A 20-in TV set also has a width of 16 inches. What is its height?
Answer provided by our tutors
20 is diagonal... 16 is width
so, 16^2 +(height)^2 = 20^2
(height)^2= 144
so, height = 12 in.
12inches is the answer
