Question

In a standard television set, the screen height is 0.75 times the screen width. If a television set measures 33 inches diagonal, what is the screen width?

Answer 1

If the television set measures 33 inches diagonal, the screen width is going to be 26.4 inches. You can find the answer by using the Pythagorean theory. 

screen length equals = x
height equals ).75x

(0.75x)^2+x^2= the diagonal d^2

1.5625x^2=33^2
and then x^2= 696.96
x= 26.4
