The triangles are similar. if wz

15, zy = 12, and xy-11, find wv. round to the nearest tenth.

15.0

13.8

13.8

Step-by-step explanation:

We are given that

When two triangles are similar then

WZ=15 , ZY=12

XY=11

We have to find the WV.

Substitute the values then we get

We have to round to the nearest tenth of final answer.

The Hundredth place =5 which is equal to 5.Therefore, 1 will be added tenth place 7 and all digits on left side remain same and digit on right side of tenth place replace by zero.

Therefore, WV=13.8

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.
