A diagonal of a rectangle determines a 30 degree angle with a longer side of the rectangle.
If the sum of the lengths of the diagonals is 14 in., how long is a short side of the rectangle?
:
That means one diagonal = 7
The short side (s) will be equal to the sine of 30 degrees
sin(30) = s%2F7
s = 7*.5
s = 3.5 in is the short side of the rectangle
