Suzie starts her hike at 220 feet below sea level. When she reaches the hike she is still below level sea level at -171 feet. What was the change in evalation from evalation from the beginning of Suzi's hike to the end of the hike

+49 feet

Step-by-step explanation:

The inicial position that Suzie started her hike was 220 feet below sea level, so as this inicial position was negative, let's use the negative sign for it:

Inicial position = -220 feet

The final position of the hike was 171 feet below sea level, so:

Final position = -171 feet

So we calculate the change in elevation from the beginning to the end of the hike by making the difference between the final position and the inicial position:

Change in elevation = Final position - Inicial position = -171 - (-220) = -171 + 220 = +49 feet

The change in elevation was +49 feet (the positive sign indicates that the movement was upwards, in direction to "above sea level")

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.
