a (of llgram) =bh

18 = 6h

h= 3

3-5-6 triangle is always 30/60/90 (provided the base is 1/2 the hypotnuse)

Answer should be 60

Shouldn't one angle be 30 degrees ...
Sin A = 3/6 = 0.5 = sin (60)

In a 30-60-90 right triangle, the side opposite the 30 degree angle is 1/2 the hypotenuse, and the side opposite the 60 degree angle is (1/2) sqrt(3) times the length of the hypotenuse

so, one of the angles will be 180-30 = 150

Yep, I confused the lenghts. 150 or 30 here. Would have been nice to see the answer choices upfront.
