Answer:
In a 30-60-90 triangle, the hypotenuse (or diagonal) times .5 equals the short side or the width (height) of the tv.
width or height = 15
and the "medium" side = 30 * (sqrt (3) /2).
medium side = 30 * (1.732 / 2)
medium side = 30 * .866
medium side (or width)= 25.98
so the exact width and height is:
width = 25.98
height = 15
