the side opposite from the 30 degree angle is

Answer 1

side opposite 30 degrees in a right triangle is the shortest side = 1/2 the hypotenuse.

60 degrees angle is opposite 30 degrees if it's a right triangle

If it's not a right triangle the opposite angle could be 0 < theta < 150 degrees

or on average 75 degrees

then the shortest side is the one opposite the smallest angle which could be less than 30 degrees.
