8 + 4 : 12
 
        
                    
             
        
        
        
The length of the unknown side length, |AB|, is 6.97 
<h3>Trigonometry</h3>
From the question, we are to determine the value of the unknown side length 
The unknown side length is the hypotenuse 
Using SOH CAH TOA
We can write that 
sin 35° = 4/|AB|
∴ |AB| = 4 /sin35°
|AB| = 4 /sin35°
|AB| = 6.97
Hence, the length of the unknown side length, |AB|, is 6.97

So hmm notice the picture below
the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges
now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then

now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both

1 person did as you can see
 
        
                    
             
        
        
        
In the fomr
ax+by=c
-a/b=slope
4x-8y=11
a=1
b=-8
slope=-4/-8=4/8=1/2
