<h2>
Answer: -1.469</h2>
This trigonometric function can be written as:
 (1)
   (1)
Firstly, we have to solve the inner parenthesis:
 (2)
   (2)
Substituting (2) in (1):
 (4)
   (4)
Finally we obtain the value:
 
   
 
        
        
        
Given:
The figure of two quadrilaterals.
In 
In 
To find:
Whether the figures are congruent, similar or neither.
Solution:
Ratio of corresponding sides are:


Similarly,




And,


Clearly,  .
.
All corresponding sides are not proportional.
Therefore, the figures are neither similar nor congruent. Hence, third option is correct.
