Sally wants to purchase some new school supplies. notebooks cost $3 each and pens cost $2 each. sally is not allowed to purchase more than 12 items. sally knows that she will need at lease 4 notebooks and at least 5 pens to be prepared for school. define your variables for x and y.

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
