Question

Please help. Will Fan and Medal ANYONE who helps me.

Answer 1

Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one wall in the plan is 17 inches. The length of the diagonal of the floor of the room in the plan is approximately 18.79 inches.

Is the room in the shape of a square? Explain how you determined your answer. Show all your work.

Answer 2

18.79

Answer 3

sorry i don't understand. please explain

Answer 4

17=24.04

Answer 5

the diagonal of a square with sides 17 would be 24.04...

Answer 6

so i writ e it like this
17=24.04
the diagonal of a square with sides 17 would be 24.04

Answer 7

hello @princesslovey

Answer 8

18.79 is the diagonal

Answer 9

wait. please write it all together. I'm sorry if i'm aggravating you but it's all over the place.

Answer 10

^ The above is correct. To prove this is a square, you need to prove that the perpendicular side is 17 inches.

You have two lengths of a right angled triangle, so Pythagoras' theorem is the way to go.

c^2 (the diagonal squared) = a^2 (one length squared) + b^2 (the other length squared)

Try substituting your values into that equation

Answer 11

hello @Australia.J.

Answer 12

yeah i'm here

Answer 13

tryna figure it out

Answer 14

I guess they got it :)

Answer 15

who

Answer 16

I would think that you would use the Patagonian theorem to solve for the missing side, and that might answer your question. If a^2+b^2=c^2
and c is the diagonal, then c^2-a^2=b^2

Answer 17

okay

Answer 18

u get it now

Answer 19

yeah sorta.
