Answer 3

work out the height using trigonometry
and its 12 * height

Answer 4

\[{{12\ cos(120)}\choose{0\ sin(120)}}^{0}_{12sin(120)}=12sin(120)-0=12sin(120)\]

Answer 5

drop the negative for area tho ;)

Answer 6

tanx its for geometry
4√3.is the anwer

Answer 7

0 1 2 3 4
0 30 45 60 90

sin(120) = -sqrt(3)/2 if my memory device serves me

Answer 8

you sure it aint 6sqrt(3) for the area?

Answer 9

i forgot an 8 lol ... hmm

Answer 10

height = 8sin(60) in the drawing

base times height = area

12 * 8sin(60) = 96sqrt(3)/2
