Answer:
the answer is b i thinkk.
angle x is an exterior angle of the triangle
The elevation when the boiling point of water is ° is 12790.70 feet
Step-by-step explanation:
Let every 1,000 feet of elevation be . Hence, we can write
Where is the boiling temperature of water at different elevations
Now, to the determine the elevation when the boiling point of water is °.
We will determine by putting °.
Hence,
Since represents every 1,000 feet of elevation, then the elevation when the boiling point of water is °
× feet
Hence, the elevation when the boiling point of water is ° is 12790.70 feet
