Correct answer is

Step-by-step explanation:

Given a 2x2 matrix with I row as -2 and 1

and II row as 3 and 2

We have to do the row transformations as

R1 = -3R1

Multiply row I by -3 we get the elements as 6 and -3

Hence new matrix will have I row as 6 and -3 and

II row as 3 and 2

So answer is.

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.
