Jovante decides to start a business by making buttons and selling them for 25 cents each. the button machine costs $125 and the materials for each button cost 10 cents.

If he wants to sell buttons, say 40 buttons, he will get a profit of 1000 cents. And one dollar is equal to 100 cents so he only earns 10 dollars. However, the costs for the machine are 125 dollars. Therefore he has a loss of 115 dollars.

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.
