**Navigation Questions**

So I can't figure out few Q's about variation and deviation.

I need to know this by tommorow.

CH is 120°. Deviation is +4°. Variation is 5° W. Wind correction angle is 8° Right. TT is: (choose below)

111°

127°

113°

129°

CH is 224°. Deviation is -3°. Variation is 4° W. TH is:

217°

223°

225°

231°

CH is 317°. Deviation is +3°. Variation is 5° W. Wind correction angle is 10° right. TT is:

309°

305°

329°

325°

CH is 098°. Deviation is +2°. Variation is -8° and drift is 5° Left. TT is:

087°

093°

097°

109°

So what is the rule?

It might be easy for you guys but I'm stuck with these.

I still hav few questions left but I need to search for it.

Thanks for helping out!

Distances

Calculate the distance AB via the shortest route. A: 160°56'E and 089°54'N, B: 019°04'W and 066°13'N.

2 points are located on the same longitude and on 34° 30' N and 26° 20' S respectively. The distance between both points is:
