The Grand Canyon Skywalk at Eagle Point is a horseshoe shaped steel frame with
glass floor looking down to the Grand Canyon below. The Skywalk extends 70 feet
over the canyon rim and is 10 feet wide. The walkway consists of a semicircle with a
straight portion on each side as indicated in the diagram below.
1. [5 pts] In order to prevent anyone from falling over the sides, a new railing
needs to be installed. How many linear feet of railing are needed to line
both sides of the walkway? (Round your final answer to 1 decimalplace
and any intermediate calculations to 2 decimal places. Be sure to
include units.)

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.
