9. Each set of ordered pairs shows a relation. Which set also represents a
function?
A {(1,2), (2,3), (2,4),(3,5),(4,6)}
B {(1,2), (2,3), (3,4), (3,5),(4,6)}
© {(1,2), (2,3), (3,4),(4;5), (5,4)}
0 {(0,1),(1,2), (2,4),(3,5),(1,6)}

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

is there more to this question?
