A construction crew needs to pave a road that is 206 miles long. The crew paves 7 miles of the road each day. The length, L (in miles), that is left to be paved after d days is given by the following function. I(d) = 206-7d Answer the following questions. oo (a) How many miles of the road does the crew have left to pave after 12 days? I miles (b) If 143 miles of the road is left to be paved, how many days has the crew been paving the road? 1 days

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.

x = 23.78
