I think x= 65 I hope this helped
        
             
        
        
        
If you are looking for the area the answer would be 24 ft. tall because 6*4 is 24
        
             
        
        
        
I believe the answer is c
        
                    
             
        
        
        
Answer:
58 feet.
Step-by-step explanation
Since the angle given is across from the length we need to find and we are given the hypotenuse, we use sine.
Sin(46)=x/80 where x is the height of the triangle and 80 is the hypotenuse. 
80sin(46)=x
x=57.55 or 58 feet.
 
        
                    
             
        
        
        
It is 1/1000 or 1/10∧-3
that is because whenever there is a negative exponent put it as the denominator and the numerator by default, if there isn't any, should be one. 
so put it under and then figure it out
