Points are said to be collinear if they are on the same line. The possible lengths of CD are 31.6cm and 12.6cm

Given that:

$CE=22.1cm$

$DE = 9.5cm$

<u>If E is between C and D, then:</u>

$CD =CE + DE$

So, we have:

$CD =22.1cm + 9.5cm$

$CD =31.6cm$

Another possible scenario is:

<u>If D is between C and E, then:</u>

$CE = CD + DE$

Make CD the subject

$CD = CE - DE$

So, we have:

$CD = 22.1cm -9.5cm$

$CD = 12.6cm$

Hence, the possible values of CD are 31.6cm and 12.6cm

To find the resultant vector you need to add the horizontal and vertical components of each individual vector.
Cosine for horizontal, Sine for vertical.
$v = \ \textless \ |v|cos \theta, |v| sin \theta\ \textgreater \$
Where |v| is magnitude or length of vector.
Lets look at first ranger station. First vector has magnitude 4.5 with angle of 90.
Next has magnitude of 8.1 with angle of 125.
$F_1 = \ \textless \ 4.5 cos(90)+8.1 cos(125) , 4.5 sin(90) + 8.1 sin(125) \ \textgreater \$
$F_1 = \ \textless \ -4.646, 11.135\ \textgreater \$
Find magnitude:
$|F_1| = \sqrt{((-4.646)^2+(11.135)^2} = 12.065$
Do the same with 2nd ranger station:
$F_2 = \ \textless \ 7.5 cos(20) + 5.3 cos(100), 7.5 sin(20) + 5.3 sin(100)\ \textgreater \$
$F_2 = \ \textless \ 6.127, 7.784\ \textgreater \$
$|F_2| = \sqrt{(6.127)^2 + (7.784)^2} = 9.9$

Therefore the 2nd ranger station is closest to starting point.
