Could someone help me, please? I’ll appreciate it.

alright got ur answer :)

x = 9 as i told u :)

there are 2 ways to do it:

1) Linear equations ( the one i showed u):

5x+45 = 90

5x = 45

x = 9

2) Pythagorus theorem ( the one in the attachment)

x = 9

HOPE IT HELPS!!

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.
