Answer:
   x = 40
Step-by-step explanation:
The angle bisector divides corresponding sides proportionally.
   x/16 = 25/10
   x = 16(25/10) . . . . . multiply by 16
   x = 40
 
        
             
        
        
        
First subtract  2 revolutions from the - 840 :-    (- (840-720)  = -120
This gives  sin -120  which is in the 3rd quadrant of the unit circle
sin -120  =  - sin 60  = - sqrt3/2
        
             
        
        
        
Hi,
81 is 37.5% of 216.
"1. We assume, that the number 37.5 is 100% - because it's the output value of the task.  
2. We assume, that x is the value we are looking for.  
3. If 100% equals 37.5, so we can write it down as 100%=37.5.  
4. We know, that x% equals 81 of the output value, so we can write it down as x%=81.  
5. Now we have two simple equations:
1) 100%=37.5
2) x%=81
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=37.5/81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 81 is what percent of 37.5
100%/x%=37.5/81
(100/x)*x=(37.5/81)*x       - we multiply both sides of the equation by x
100=0.46296296296296*x       - we divide both sides of the equation by (0.46296296296296) to get x
100/0.46296296296296=x  
216=x  
x=216                           "
Have a great day!
