Answer:
x = 5.5
Step-by-step explanation:
Using a trig ratio, you can use sin, which is opposite over hypotenuse. 
Now, multiply both sides by 11

this simplifies to x =
or 5.5.
Since sin30 is
radians, it can be written as
.
So 12 out of 32=12/32=6/16=3/8
percent means parts out of 100 so
x/100=x%
3/8=0.375/1
0.375/1 times 100/100=37.5/100=37.5%
answer is 37.5%
