Alice syas that all the factors of are even

Alice says that all the factors of 8 are even .

Solution:

Absolutely Alice is wrong.

As we know that the factors of any number are those numbers which can divide that number completely.

so, factors of 8 are 1,2,4 and 8.

Here one can see easily from all the four factors of 8 ,2,4,8 are even but 1 is odd.

so,this is the example and Explanation that statement of Alice is wrong.

Step-by-step explanation:

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.
