Answer: Y= 1.6
Step-by-step explanation: 1.6 + 0.4 =2
It’s most likely answer D
<span>A 2% solution of chlorohexidine added to 126 oz of water. The total oz 128.
Solute: chlorohexidine, 2%=0.02
solvent: water (0%)
Concentration, C, volume V
CV=c1v1+c2v1
128C=0.02*2 + 0.00*126 = 0.04
Concentration
C=0.04/128 = 0.0003125 = 0.03125%</span>
X= 180 - 157
= 23
Therefore, X is 23 degrees. A straight line has an angle of 180 degrees, so subtracting the given angle would give you X.
