Hard work you got there keep looking !
        
             
        
        
        
So first step is to simplify everything outside of the radicals.
6*2=12
:. The expression is
 __ __
12*\| 8 * \| 2
Now we know that
 __ __ __
\| 8 = \| 4 * \| 2
And
 __ __
\| 2 * \| 2 = 2
And
 __
\| 4 = 2
So if we incorporate what we know into the equation, we can figure it out.
So let's first expand the radical 8.
 __ __ __
12*\| 4 * \| 2 * \| 2
Now by simplifying the radical four and combining the radical twos, we can get all whole numbers.
12*2*2
Which equals 48.
Answer:48

We need to solve for the angles of the smaller triangle in
order to solve for the angle of the larger triangle which would help us solve
the missing measurement of a side.
Given:
51 degrees.
Cut the triangle into two equal sides and it forms a right
triangle. All interior angles of a triangle sums up to 180 degrees.
180 – 51 – 90 = 39 degrees
39 degrees * 2 = 78 degrees.
Angle Q is 78 degrees. 
In the bigger triangle, 4.3 is the hypotenuse. We need to
solve for the measurement of the long leg which is the opposite of the 78
degree angle. 
We will use the formula:
Sine theta = opposite / hypotenuse
Sin(78 deg) = opposite / 4.3
Sin(78 deg) * 4.3 = opposite
4.21 = opposite. This is also the height of the triangle.
 
Area of a triangle = ½ * base * height
A = ½ * 3units * 4.21units
A = 6.315 square units.
