Question

If P(5,-4) Q(8,5) and R(2,-1) are the vertices of triangle PQR , M is midpoint of QR and A is a point on PM jointed such that PA /AM= 2/1 find the coordinate of A​

Answer 1

Let Q and R be the base vertices and P be the vertex at the apex. First find the midpoint of the Q & R as the median from apex joins the midpoint of base line. Midpoint of QR is (5/2,-3/2). Now, Let us find the slope between the midpoint of these Two and P i.e., 11. Put it in the slope equation formula y-y1 = slope × (x-x1). (x1,y1) can be Vertex P or Midpoint of QR. equation comes to be 11x-y-29=0.

Answer 2

Answer:

5,0

Step-by-step explanation:

m is mid point of qr

therefore, m=8+2/2, 5-1/2

m=5,2

a is a point on m such that pa/am=1/2

therefore,

a=mx2+nx1/m+n, my2+ny1/m+n

a=10+5/3, 4-4/3

therefore, a =5,0
