James completely covered a square poster board using 68.2 in. of cardstock. Which measurement is closest to one side of the poster board in inches?
Answer?

17inches

Step-by-step explanation:

If James completely covered a square poster board using 68.2 in. of cardstock, this means that the perimeter of the square box is 68.2in.

To get the measurement if one side if the box we will use the formula for finding the perimeter of the square.

P = 4L

L is side length of the square box

68.2 = 4L

L = 68.2/4

L = 17.05in

.hence the measurement closest to one side of the square box is 17inches

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.
