Answer:
The answer is 
Step-by-step explanation:
We have to:

So, if we take the 60 degree angle of the smallest triangle, we have to:

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

Then:



 
        
             
        
        
        
Answer:
12.43ft
Step-by-step explanation:
  From the given diagram, we simply apply the sin rule
According to the sine rule
 = 
    y is the side y 
     y° = (90 - 43) = 47 
     z = 17 
     z° = 90
Input the parameters and solve; 
             
        ysin 90 = 17 sin 47
          y = 12.43ft

Answer:
21 cm
Step-by-step explanation:
The perimeter is the length of the outside of a shape. In this case, we can simply add up all the edges and multiply by .5(the length of one edge). 
Horizontal Edges: 22
Vertical Edges: 20
Total: 42
Perimeter =
