<u><em>The correct expression is</em></u>

we know that


substitute in the expression above

The ratios of the sides
hypotnuse=2x
x=short leg (oposite 30)
x√3=long leg (oposite 60)
long leg=x√3
to find x, divide by √3
longleg/√3=short leg=x
rationalize denomenator, times √3/√3
(longleg√3)/3=short leg
the legnth of the short leg is
(longleg√3)/3
