Answer:
22
Step-by-step explanation:
The sum of the interior angles equal the number of sides minus 2 times 180.
(22-2)180 = 3600
20(180) =3600
3600 - 3600
First of all, we need to find the slope of the given line, writing it in the
form and reading the
coefficient:

So, the slope is 
If a line with slope
is perpendicular to a line with slope
, the following relationship holds:

So, the slope of our line must satisfy

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope
and a point
of a given line, its equation is given by

So, if you plug your values, you have
