Answer 1

Answer:

Sorry yr I don't know this answer because I m in class 8

Answer 2

Answer:

(4.5,8.5) or (9/2,17/2)

$\sqrt{ {a}^{2} + {b}^{2} }$

Step-by-step explanation:

q.1

(x1+x2)/2 , (y1 + y2)/2 (formula for midpoint)

(6+3)/2 , (8+9)/2

9/2 , 17/2

q.2

you can see that they form a right triangle

by joining 0,0 to ab, and a to ab

so hypotenuse equals the distance between them

and by pythagoras theorem h^2=base^2+height^2

distance^2=a^2 + b^2

therefore distance = root(a^2 + b^2)
