There are 92 elements that are found in nature. Roughly 80 of those are capable of combining with each other to make compounds, so there are a lot more than 92 compounds.
Example: Take carbon and hydrogen. (please)
Carbon and hydrogen combine to make methane, ethane, propane, pentane, hexane, heptane, octane, butane, and several more 'tanes'.
And if you have some oxygen along with the carbon and hydrogen, you can
make all the alcohols there are, plus vinegar.

Answer:
The answer to your question is 636.6 ft
Explanation:
Data
base = 425 ft
angle = 39°
See the picture below
1.- Divide the triangle to get two right triangles.
Now the superior angle will measure 19.5° and the opposite side will measure 212.5 ft
2.- Use the trigonometric function sine to find the hypotenuse
sin 19.5 = 212.5/hyp
solve for hyp
hyp = 212.5 / sin 19.5
Result
hyp = 212.5/ 0.333
hyp = 636.6 ft
I think it false. Sorry if i'm wrong.
