Atrampoline was originally priced at $72, but brennan waited to buy it until the trampoline was on sale for 70% off. if he paid 5% sales tax on the sale price, how much did he pay in total?

$52.92

Step-by-step explanation:

The sale price was 0.70($72), or $50.40.

Then the price paid, plus the tax, is 1.05($50.40), or $52.92.

You could, if you wished, do all these calculations on one line:

1.05(0.70)($72) = $52.92.

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.

i can answer this question sweetie!
