Aconcert crew needs to set up some
chairs on the floor level. the chairs are to be placed in a square pattern
consisting of four square sections. if one of the square sections holds
chairs, how many chairs will there be along each length of the larger
square?

the four sections would be 60 x 60 since 900 is 30 x 30

double it

60 x 60

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.

i need more info. are you looked to see there mph? how much they deliver? how far they go?
