You need this key result: in any polygon, the sum of the interior angles is
where 
is the number of sides of the polygon.
Your polygon has seven sides, and the measures of all angles are given. So, we can write
Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.
We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:
and we can solve this equation for 
by dividing both sides by 30:
Finally, the required angles is

The equivalent numbers of 12/20 are 60% and 0.60
<h3>How to convert the fraction?</h3>
The fraction expression is given as:
12/20
Multiply the fraction expression by 100%
So, the expression becomes
12/20 * 100%
Evaluate the product
60%
Express as fraction, again
60/100
Evaluate the quotient
0.60
Hence, the equivalent numbers of 12/20 are 60% and 0.60

Solution:
The function is given below as
To figure out
To do this , we will substitute x= 2x-1 in g(x)
Hence,
The composte function will be
Step 2:
To figure out the domain,
In mathematics, the domain of a function is the set of inputs accepted by the function.
Hence,
The domain of the function is
Answer:
3240°
Explanation:
The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.
