A hiker starts walking due west from Sasquatch Point and gets to the Chupacabra Trailhead before she realizes that she hasn't reset her pedometer. From the Chupacabra Trailhead she hikes for 5 miles along a bearing of N55°W which brings her to the Muffin Ridge Observatory. From there, she knows a bearing of S65°E will take her straight back to Sasquatch Point. How far will she have to walk to get from the Muffin Ridge Observatory to Sasquatch Point?

Respuesta :

okay so u only know one distance in this triangle! but u can find all three angles and get a side angle angle or SAA triangle and can solve with the law of cosines or sines from there

what is the side? that's 5 miles

what are the angles?

given north is at 90°, 57° west of north means one angle is 90° +50° = 147°

given south is 90° -69° = 21°

third angle is 180° -147° -21° = 12°

this means 12° is opposite 5 miles

hence distance from muffin observatory to chubacabra trail is 5 miles

distance from sasquatch point to muffin observatory is found from the law of sines

d /sin(147°) = 5 /sin(12°)

d = 5 *sin(147°) /sin(12°) = 13.10 miles

then distance from sqsuqtahc point to chubacapra trail is

d /sin(21°) = 5 /sin(12°)

d = 5 *sin(21°) /sin(12°) = 8.62 miles

This exercise is necessary to have a knowledge of geometry in order to analyze the points and calculate the distance of each station, in this way we find that:

A) [tex]13.10 miles[/tex]

B) [tex]8.62 miles[/tex]

First, it is possible to see that the three points form a triangle and to do this we now need to find the angles so that we can then make the calculations given in advance, that is, we will have the angles as:

Given north is at 90°, 50° west of north means one angle is: 90° +50° = 147°

Given south is:  90° -69° = 21°

Third angle is :180° -147° -21° = 12°

This means 12° is opposite 5 miles

A) Distance from Sasquatch Point to Muffin Ridge Observatory is found from the law of sines:

[tex]d /sin(147\°) = 5 /sin(12\°)\\d = 5 *sin(147\°) /sin(12\°) = 13.10 miles[/tex]

B) Then distance from  Sasquatch Point to Chupacabra Trailhead is:

[tex]d /sin(21\°) = 5 /sin(12\°)\\d = 5 *sin(21\°) /sin(12\°) = 8.62 miles[/tex]
