Prove
Subtract tan(10) from both sides
Factorize the right hand size
Rewrite as:
Divide both sides by 
In trigonometry:
So:
can be expressed as: 
gives
In trigonometry:
So:
Because RHS = LHS
Then:
has been proven
This should be the answer
3.5 x 10^7
Your answer would be the first on because when you set up your equation you can find 4 by dividing 42,980 by 10 4 times wich will give you 10^4 when you divide exponents you subtract so iwill look like this....
5x10^6
----------= 1.25x10^2
4x10^4
28.87 and .122
Hope this helps
