Could someone pleasee help me in this? May the first answer be the brainliest! :)

39.9869 (they would probably round it to 40)

Step-by-step explanation:

Tangent is the main ratio that is used to determine the angle of depression. It may be found by using this equation tan y is equal to opposite divided by the adjacent side. The opposite side, in this case 52m, is the height of the cliff. At the angle of depression, the observer's line of sight would be above the horizontal. In simple, If you are viewing at an object below the horizon then the angle between the horizontal and your line of sight is the angle of depression.

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.
