A ship sails due north 300km to from position A to position B. It
then sails 450km due east to
position C. What is the bearing
and distance the ship would need
to sail to go directly from C to A?

c

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
