If you expand the square, you have
Simplify the right hand side:
Cancel the -3x appearing on both sides:
Multiply both sides by 4:
Consider the square root of both terms (using the doubles sign):
Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:
I simplified the problem to:
I combined like terms:
I moved all x to one side and all other constants to the other:
I divided by 3/2 (1.5) on both sides to isolate x:

By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.
Thus,
is a constant which can be found using a calculator:
with calc in pc: view → scientific → 27→sin = 0.45399,
thus x=34/0.45399=74.89
Answer: 74.89
