Addition is the first step, since you can’t do anything in the parenthesis because it’s not possible to add an unknown value with anything nor effect it. You just need to add first then subtract just like the PEMDAS method.

Answer:
Polygon Exterior Angle Sum Theorem. If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Answer:
sorry happy Halloween btw :D
Given line ax+by=c and point (h, k), the perpendicular line through (h, k) can be written as
b(x-h) -a(y-k) = 0
In order for this to be in standard form, it must be rearranged somewhat, and any common factors removed.
We can start with
20(x-8) -5(y-3) = 0
4x -32 -y +3 = 0
4x -y = 29
The standard-form equation of the desired line through (8, 3) is
4x -y = 29
