The sum of the external angles of every polygon = 360 degrees
So the n-gon must have its interior angle sum = 360 degrees also.
So what polygon has interior angle sum = 360?
Cos(theta)=a/h
Cos(theta)=12/13
Theta=cos^-1(12/13)
Theta=22.62 degrees

The slope of the line in its simplest form is 3.
The slope of a line is
.
We need to find the slope of the line in its simplest form.
<h3>What is the slope?</h3>
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope is often denoted by the letter m; there is no clear answer to the question of why the letter m is used for slope.
Select any two points on the line like A and B.
From the below figure it is clear that
Rise = Change in y = -2-(-5) = 3
Run = Change in x = 9-0 = 9
Now, 
Therefore, the slope of the line in simplest form is 3.
