U = {a, b, c, d, e, f, g}
A = {a, c, e, g)
B = {a, b, c, d]
Find A U B'

the line of

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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
