In this instance the distance will be the hypotenuse of a right angle triangle.
x = 300/sin30 = 600
They are 600 ft away from each other
        
             
        
        
        
You know that 1 km=1000 m, then the length of the road  km is
 km is  metres.
 metres. 
 A group of 8 people are picking up litter along the road and each person is assigned an equal section of the road. The whole road has length 800 m, then for each person will be assigned 800:8=100 m of the road.
If you want to know the length of each part in km, then 1 m=0.001 km and 100 m =1 m·100=0.001 km ·100=0.1 km. 
 
        
             
        
        
        
The GCF of 18 and 72 would be the first step.
the gcf is 18
So we we now have 18 (x^2y)(xy)
factor both variables
18xy would be the gcf
        
             
        
        
        
12c - 36 + 27 + c - 9c
= 4c - 9
        
                    
             
        
        
        
C
you have to find the area Length* width then divide it by the total amount
42x25.5=1071
1071/ 771.12=1.39
