How many lines of symmetry are found on this figure?
A) 2
B) 4
C) 6
D 8

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

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
