Geographers use negative numbers to represent points below sea level and positive numbers to represent points above sea level. a penguin dove 3.5 meters below sea level to catch dinner for his kids, who are sitting on an iceberg 12 of a meter above sea level.
what is the difference in elevation between the penguin and his kids?

a
2 meters
b
1 meter
c
3 meters
d
4 meters

4 meters

Step-by-step explanation:

I think that's is I'm not too sure

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.

you would need to know all the numbers that are on there
