You just bought a dog and you want to put a fence up in your backyard so fido doesn't run away. one side of the yard needs 20 feet of fence, another 50 feet of fence, and 2 sides needs 75 feet of fence. how much fence do you need to enclose your yard?

170 feet

Step-by-step explanation:

add 75+75+20

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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.
