PLEASE SMART PPL HELP!

Step-by-step explanation: Add like terms first. 550 -25x = 35x + 10

Then add 25x to both sides... 550 = 60x + 10, Then subtract 10 on both sides... 540 = 60x, Finally, divide by 60 on both sides to get x = 9.

its D

Step-by-step explanation:

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.
