Unknown sides are #6sqrt2, 6sqrt6#

Three angles of the right triangle are

#A = 30^0, B = 60^0, C = 90^0#

Sides will be in the ratio,
#x : x sqrt3 : 2 x# as May be seen from the diagram above.

Given hypotenuse # 12sqrt2 = 2x#

#x = (12sqrt2) / 2 = 6 sqrt2#

Side opposite to #30^0 = x = 6sqrt2#

Side opposite to #60^0 = x sqrt3 = 6 sqrt2 * sqrt 3 = 6 sqrt6#
