40°
Step-by-step explanation:
because angle In an isosceles triangle base angles are same and angle in a triangle add up to 180° and angle on a straight line add up to 180°
hope this helps:)
Answer:
Step-by-step explanation:
lets say in the shown triangle x=165
so speed
and
Also since distance = speed* time
time = pi minutes = pi/60 seconds
y =
y =
Now using the pythagorean :
<u>derivate the equation so we get :</u>
m/s
So Rate of change = <u><em>25.387 m/s</em></u>
Given the equation:
You know that a lab technician finds that a sample of fluid has this pH:
Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:
1. Substitute the pH given in the exercise into the equation:
Multiply both sides by -1:
2. Solve for:
Remember that, by definition:
In this case, you can identify that:
Hence, substituting values and simplifying, you get:
Therefore, the answer is:
