19.   The size of a computer monitor is given by the length of the diagonal of the screen. The ratio of the height to the width of wide-screen monitors is 9:16. Find expressions for the width and height of a wide-screen monitor in terms of the length of its diagonal.  (1 point)

anonymous1 · Answer

The ratio of the height to the width is 9:16. It means that the height and the width are proportional to 9 and to 16.
So, we can write the height and the width respectively as 9x and 16x, where x is some positive real number.
Look the following image:
