    why don't you add 40 degrees to S 60 W to get S 100 W that does not look standard, I would say bearing 280 degrees or maybe N 80 W ?

    But azimuth starts with 0 degrees means North, 90 means East, 180 South and 270 is West A is easy. Can you try?

    for A. N. 20 DEG. 10 SEC. E that means start at North and turn 20 degrees 10 secs towards the east. That is exactly how azimuth goes. Can you try again for A?

    C N 10 DEG. 30 SEC. W. Are you sure about 30 seconds? It goes Degrees, Minutes, Seconds 60 seconds in a minute, and 60 minutes in a degree (that means 1 second is 1/3600 degree, which is a very tiny angle)

    If it were N 10 deg, 30 min W then your answer c i got 349.5, would be correct. but if it is 30 seconds, no

    The first one shows S 60 W that means start at South and turn 60 degrees toward West. Can you change that to azimuth (0 to 360 degrees)? Remember South is 180 degrees and as you turn toward West (at 270) the angle gets bigger.

    I don't want to confuse you. Let's first answer one question The very first one. It says S 60 W and then turn another 40 degrees. S 60 W is the same as 180+60= 240 add another 40 degrees: 240+40= 280 so the answer is 280 degrees or N 80 W

    N 58 E is 58 degrees from North. Now add 53 more degrees to get to H. If they want azimuth, it would be 58+53= 111 degrees Notice that this is S (180) then 69 degrees towards East or S 69 E

    to find AB, we need to know the angle between N 75 W and B. Did they give it?

    OK then N 75 W + 75 gets you to North (0 deg). we still have 15 more degrees. So the answer is either 15 degrees azimuth or N 15 E ( I am not sure which format they want) what is the angle between S 40 E and CD in the right picture?
