36

Step-by-step explanation:

This questions tests for the fundamentals of counting.

Let's say event can be done in X ways and event can be done in Y ways, therefore the total number of ways and can be done is given as .

Applying this counting principle in our case, the total different sandwiches is obtained as the product of the individual sandwich types.

36 different sandwiches can be made.

the perimeter is increased by a factor of 2

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.
