What are the coordinates of the point on the directed line segment from (-8, -1) to (6,-8) that partitions the segment into a ratio of 3 to 4?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
