Answer: Choice A) 143 degrees
To get this answer quickly, you subtract the given angle (37) from 180 to get 180-37 = 143
The more longer answer would look something like this
x+37 = 180 .... the two supplementary angles add to 180 degrees
x+37-37 = 180-37 .... subtract 37 from both sides
x+0 = 143
x = 143
where x is the measure of angle ZXW
The answer actually is 28. But I think you should give the other guy brainliest.

The concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.
<h3>What is pH value?</h3>
The pH value shows that how much a solution is acidic or basic. The range of the pH value lies between the 0-14.
The pH value can be calculated with the following formula.
![\rm pH=log[H^{+}]](https://tex.z-dn.net/?f=%5Crm%20pH%3Dlog%5BH%5E%7B%2B%7D%5D)
Here, [H⁺] is the molar hydrogen ion concentration.
The pH of lemon juice at 298 K is found to be 2. 32. Put this value of pH in the above formula as,
![\rm 2.32=log[H^{+}]\\\ [H^{+}]=4.79\times10^{-3} \rm \; M](https://tex.z-dn.net/?f=%5Crm%202.32%3Dlog%5BH%5E%7B%2B%7D%5D%5C%5C%5C%20%5BH%5E%7B%2B%7D%5D%3D4.79%5Ctimes10%5E%7B-3%7D%20%5Crm%20%5C%3B%20M)
Hence, the concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.

Answer: The distance in the map is 19 inches.
Step-by-step explanation:
On the map. 2 inches represent an actual distance of 64 miles.
The actual distance between town A and town B is equal to 608 miles, we need to divide this distance into groups of 64 miles.
N = 608/64 = 9.5
And each one of those 9.5 groups is represented with 2 inches in the map, then the distance in the map is:
d = 9.5*2 inches = 19 inches.
