The sine of 30° is  0.5 .
Angles don't have y-values, and neither do their sines.  But
IF you draw a graph of the sine function, AND the angles 
(the independent variable) are marked off on the x-axis of 
the graph, AND the value of the sine function of each angle 
(the dependent variable) is marked off on the y-axis of the 
graph, THEN the y-value corresponding to the angle of 30° 
would be displayed as 0.5 . 
        
             
        
        
        
Hope this helps you out!!!!!
 
        
        
        
Firstly we calculate 37% of 4300
so 37% of 4300=37×4300/100=1591
now 1/5 of 1591= 1×1591/5= 318.2
        
                    
             
        
        
        
1. What is the opposite of -2?  2
2. When we add opposites together they will always equal = ? 0
This is also known as what ?
additive inverse 
Adding with integers with SAME signs.
-8 + -3 = -11
-12 + -15 = -27
-3 + -9 + -25 = -37
