Please help me. I don’t understand this problem.

d = 637 ft below the surface

Step-by-step explanation:

Given

P = 14 + d

To find d when P = 308, then

14 + d = 308 ( subtract 14 from both sides )

d = 294 ( multiply by 13 to clear the fraction )

6d = 3822 ( divide both sides by 6 )

d = 637 ft

step-by-step explanation:

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.
