Answer: 204.12 inches
Step-by-step explanation:
 We can find the lengths of the unknown sides by applying these identities:
 
 Observe the image attached. To find "a" we need to substitute the following values into  :
:
 
 And solve for "a":
 
 To find "b" we need to substitute the following values into  :
:
 
 And solve for "b":
 
  To find "c" we need to substitute the following values into  :
:
 
 And solve for "c":
 
 Since the triangle on the left is Isosceles, then:
 
 Therefore, the perimeter is:
 
 
 
 
                                
             
                    
              
              
                
                
Answer:
=204.13 inches.
Step-by-step explanation:
Using the side x, we can use sine to find the hypotenuse of the triangle with the angle marked 30°.
Sin 30 =x/hypotenuse.
sin 30 = 27/hyp
hyp= 27/sin 30
=54 inches
We can also find the adjacent as follows.
Cos 30 = adjacent/ 54
Adjacent= 54 cos 30
=46.77 inches
Using the angles marked 45 we can find the hypotenuse of the isosceles triangle.
sin 45= x/hypotenuse
sin 45 =27/hypotenuse
hypotenuse = 27/sin 45
=38.18 inches
The hypotenuse of both the triangles making the isosceles triangle are 38.18 inches long.
Perimeter = 54+ 46.77+27+ 38.18+38.18
=204.13 inches.
