How do I do this I need help fast

the answer is 7:6 :)

Step-by-step explanation:

scale factor = 1.5

side DE / FD = 9 / x

sides BC / AC = 6 / 7

ratios are the same

therefore side FD = 10.5

side AB = 8

scale factor = 12 / 8 = 1.5 or 3/2

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

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.
