Problema Solution

A television screen measures 58 inches diagonally, and its aspect ratio is 4 to 3. Find the width and the height of the screen. (Round your answers to one decimal)

Answer provided by our tutors

let widht is x and height is y 

     x:y = 4 :3

      x/y = 4/3  

       x = 4y /3

     also x2 + y2 = 582

            16y2/9 + y^2 = 58 ^2

 y ^2  =  (9 * 58 ^2)/ 25

y = 34.8

                        x =46 .4
