Answer: The length of the bottom left side is 14.
To find the length of this side, we need to know the relationship between the different sections when chords cross each other.
The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.
Our equation can be written as:
7(8) = 4(x)
56 = 4x
14 = x
Let A and B be the mL of each solution needed.
quantity equation
A + B = 360
concentration equation
0.5A + 0.6B = 0.53(360)
use A = 360 - B for substitution in the other equation.
0.5(360 - B) + 0.6B = 190.8
180 - 0.5B + 0.6B = 190.8
180 + 0.1B = 190.8
0.1B = 190.8 - 180
0.1B = 10.8
B = 10.8/0.1
B = 108 mL
then A+B = 360
A + 108 = 360
A = 360 - 108
A = 252 mL
