During normal sleep, a bear’s heart beats about 50 times a minute. In its deepest state of hibernation, a bear’s heart may beat 55 times in 5 minutes. During deep hibernation, how many times would the bear’s heart beat in 45 minutes?

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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.

step-by-step explanation:

probably the last option
