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?

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
