Since ABC is equilateral, all 3 sides have equal length. side AC is 8 units since side BC is 8 units. 
Line BD is placed in the middle, making D the midpoint of side AC. 
knowing this information we can determine that the length of DC is 4 units (half of AC)
since triangle BDC is a right triangle, we can use the side lengths in the pythagorean theorem to find the length of BD
a²+b²=c² where a & b = legs of triangle , and c= hypotenuse (longest side)
we are given the hypotenuse and found one leg so we can plug our values into the equation to find the third
4² + b²= 8²
16 + b² = 64
b² = 48
b = 
b= 4√3 or about 6.928 units 
hope this helped

Members possibly involved must have an equal chance of being used, come from an equivalent background, be individually assigned through a random process, and all complete the study.
        
             
        
        
        
Faucet one fills up 

 of the bathtub in one minute and faucet two fills up 

 of the bathtub in one minute. If both are one then they will fill up  

 So, 1/6 of the bathtub in one minute.
