Question

Hey mate answer my question

question no 15 (1)

Answer 1

as we know diagonals of parallelogram bisect each other

so mid point of AC = mid point of BD

A( -2,1) , C(4,b) , B ( a,0), D (1,2)

( -2+4)/2, ( 1+b)/2 = a+1)/2, 0+2)/2

1, (1+b)/2 = a+1)/2, 1

compare

a+1)/2 = 1

a+1= 2

a= 1

1+b)/2 = 1

b= 1

Answer 2

Answer:

hope it works...............................™✌️✌️
