The perimeter of a triangle is 27 inches. only 2 sides are known 12.3 and 5.4. what is the third side and what is the equation

9.3

Step-by-step explanation:

perimeter of triangles is just all sides added together so all you have to do is: add 12.3+5.4=17.7 and then subract it from 27 (27-17.7=9.3)

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.

it would take 7/10 of an hour too fill the pool.
