I need so much help with these could you help me?

  To calculate A do the arithmetic:

0.55/12= 0.04583333... so 1+ 0.5/12= 1.04583333

(0.55/12)^36= (1.0458333..)^36= 1255260948332470717506697

and 0.55/12- 1= 0,4583333...- 1= -0.541666...

p= 30000/A= -1255260948332470717506697(30000)/0.541666)Step-by-step explanation:

hope it helps here for ur help if u need something just say it

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.
