ANSWER
True
EXPLANATION
The given trigonometric equation is:

We take the LHS and simplify to arrive at the RHS.

Collect LCM on the right hand side to get;

This implies that



This identity has been verified .Therefore the correct answer is true.
 
        
             
        
        
        
The answer is III only, or D. 
We can start to solve this by knowing what the HL theorem means. The HL theorem, like its name implies, shows says that if a hypotenuse and leg of a triangle are congruent to the hypotenuse and leg of a different triangle, then the triangles are congruent. The only triangle that we see a hypotenuse congruent in is in figure III. In figure II, those congruent sides are both legs while in figure I we just see 2 congruent angles. Now in figure III, we can also see that two legs are congruent because of the reflexive property. That means that the answer is III, or D. 
        
             
        
        
        
The LCD of 1/17 and 3/14 is 14. 
1/7 = 2/14
3/14 = 3/14
2 + 3 = 5
The denominators are the same, so it will remain the same.
= 5/14 <===
5/14 is your answer.
I hope this helps! :)
