Answer:
Equivalent equation of
is
And the number of sides does a polygon have is, n =9.
Step-by-step explanation:
Given:
The sum of the interior angles, 's' in a n-sided polygon can be determined
using the formula is:
.....[1]
where n is the number of sides.
We can write the equivalent equation of [1]

Divide both sides by 180;

Simplify:

Add 2 to both sides of an equation:

Simplify, we get;
......[2]
Now, to find the value of n ;
Given: s =1260°
Substitute this value in [2] we get;
or
n = 7+2 =9
Therefore, the number of sides in a polygon is, n=9
So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
