Answer:
![[H^{+} ]= 10^{-pH}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%20%5D%3D%2010%5E%7B-pH%7D)
Step-by-step explanation:
To solve this question it is important to remember logarithm rules. That is:
![pH = -log[H^{+}]\\\\-pH = log_{10}[H^{+} ]\\\\H^{+}] = 10^{-pH}\\](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%5D%5C%5C%5C%5C-pH%20%3D%20log_%7B10%7D%5BH%5E%7B%2B%7D%20%5D%5C%5C%5C%5CH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D%5C%5C)
The square root of 50 is 7.071
Answer:
x= -10
Step-by-step explanation:
So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.
Next add all three angles (125 + x + 35 + x + 40)=180
Combine the x values to get 2x and subtract the three values from 180
Then 2x= -20, x should be equal to -10
You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again
