If tanø= -4/3 in quadrant II, what is cosø?

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

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
