Question

i have no idea about this someone help please :((

Ship A receives a distress signal from the southwest, and ship B receives a distress signal from the same vessel from the north. At what location is the vessel in distress located? Describe how you arrived at your conclusion using complete sentences. Which theorem or postulate does this demonstrate? You must show all work and steps in order to receive credit.

Answer 1

@Godlovesme Is the attached diagram part of the problem?

Answer 2

We can assume the distress signal is coming from one source at one specific location, and that it sends a signal in a straight line.

Ship "A" is receiving it from the southwest, so draw a line from "A" that goes southwest, and extend it across the page. Ship "B" Is receiving the signal from the north, so draw a horizontal line from "B" out towards the north. Extend that line too.

The place where they meet must be where the signal is.

Answer 3

yes @Directrix

Answer 4

oh wow but i was trying to do the problem

Euclid's first two postulates say that a straight line segment can be drawn joining any two points, and any straight line segment can be extended indefinitely in a straight line. If you extend the line from A directly southwest, and a line from B upward to the north they intersect at (1,2).

Answer 5

I was looking just now and found that I helped with a similar problem a year ago. The directions of the distress call were different but I think the postulates hold.

Answer 6

lol that''s where i got this part from "Euclid's first two postulates say that a straight line segment can be drawn joining any two points, and any straight line segment can be extended indefinitely in a straight line." :P

Answer 7

Reading that year-old thread again, I'm thinking about the postulate or theorem that says that two lines intersect in exactly one point. Should it have been included? Let me look at my Geometry book while you look at yours.

Answer 8

>> At what location is the vessel in distress located?

That is at the intersection of the two lines.

That is a theorem: If two lines intersect, then they intersect in exactly one point.

Answer 9

The ordering of postulates by Euclid and the ordering of Euclid's postulates in textbooks varies.
--------------------------

Euclid's Postulates

1. A straight line segment can be drawn joining any two points.

2. Any straight line segment can be extended indefinitely in a straight line.

Answer 10

but i haven't learned about Euclid's postulates i just know the postulates

Answer 11

thanks for helping :)
