The area of a hexagon is
A= a^2 (3√3)/2
we replace a with 4
A=41.57
Answer:
166°
Step-by-step explanation:
Since ∠A = ∠B,
the equation below helps to find the value of x and angle A:
- 7x + 40° = 3x + 112°
- 7x - 3x = 112° - 40°
- 4x = 72°
- x = 72°/4
- x = 18°
- ∠A = 7*18° + 40° = 166°
<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>
Numbers are n, n+2 and
n(n+2)=195
n^2+2n-195=0
Using the quadratic equation n=13
And n+2=15
