1.	3:4, find the value of 2+yORe vertices of AABC are A(6,-2), B(O, -6) and C(4, 8). Find the co-ordinates of mid-points of AB, BCand AC.either side of a 75 m high building and in line with base of building observe the angles1 60 Find the distance between the two men. (Use
Answer» Given thatA(6,-2), B(0,-6),C(4,8)mid point formal = x1 + x2 /2 ,y1+y2 /2mid point for A and B= x1 + x2/2 , y1 +y2 / 2= 6+0/2 ,-2-6 /2= (3,-4)mid point for the B and C= o+4 /2 , -6+8 /2= (2,1)mid point for A and C= 4+6 /2 , 8-2 /2= (5,3).
