Question

I mark u the best answer ​

Answer 1

Answer:

Step-by-step explanation:

given that

midpoint of line segment joining the points (5, 7) and (3, 9) is also the midpoint of line segment joining the point (8, 6) and (a, b)

we have to find a and b =?

solution:-

at first

let (x,y) are the mid point of the two points A(5,7)

and B(3,9)

here using midpoint formula

x=(x1+x2)/2 = (5+3)/2 = 8/2 = 4

and

y= (y1+ y2)/2 = (7+9)/2 = 16/2 =8

the coordinates of mid point are (4,8)

According to question ,

(4,8) is also the midpoint of points C(8,6) and D(a,b)

=> 4 = (8+a)/2 => 8= 8+a => a= 0

and also

=> 8= ( 6+b)/2 => 16 = 6+b

=> b = 16-6 = 10

so

a= 0 & b= 10 answers
