The sum of the interior angle measures of a convex polygon is 2520° . How many sides does it have?

where are the options?

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
