Answer:
is used to prove the given equation.
Step-by-step explanation:
We have given an equation:
We will consider right hand side first
tan x can be written as:
So, on substituting tan x in the left hand side of the given equation we get:
Cancel common term from denominator and numerator which is cosx we get
And we have an identity:
Hence, right hand side is equal to .
I think any irrational number would do this? I'm not positive though. Some examples may be pi or the square root of 2.

Answer:
14%
Step-by-step explanation:
<em><u>49 parts of 350 parts</u></em> do not need specifications...
= 49/350
So, 49/350 = x/100
= <u>49(100) = 350x</u>
= 4900 = 350x
= 4900/350 = x
x = 14%
