Answer:
32 students
Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German
Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)
In this case:
the maximum number of students = 15 + 17 = 32 students 
Hope this helps :)
        
             
        
        
        
Answer:
The solution is 
Step-by-step explanation:
The equation 

can be rewritten as 

and can be further simplified to 
 .
.
Now, taking the inverse sine of both sides we get: 


The value of the right side on the interval  is
 is 
 ,
 ,
which makes the equation (2) 

solving for  gives
 gives 

which is our solution.
