P- 4 equals 2, find the value of 5p - 20

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

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
