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
