Trying to measure two different angles

Postby icycoolx on Fri Jan 24, 2014 7:03 pm

I have to figure out the measure of the two different angles from the picture. If somebody could show me how to solve this type of problem then that would be great.

This was the question and there are a few others like it.

They say that you are supposed to measure the angles in degrees, minutes, and seconds. This ' stands for seconds, this " stands for minutes, and the degree symbol most people know already.

My work as follows:

60/20, 60/15, 3600/40 and 60/10, 60/12, 3600/30

I then got the answers 3, 4, 90, and 6, 5, 120

However I am not really sure what to do with these numbers or if I even figuring this out correctly.

I'm sorry, but I don't understand what you're doing. What are the fractions for? How did you get two answers for the size of the one angle? There are 60 seconds in 1 minutes and 60 minutes in 1 degree, so you add these like you add time. 40" + 30" = 70" = 1' 10" Then add the minutes from the two angles, and the degrees from the two angles. Then add all of it together, putting the 1' from the 40" + 30" in with the minutes, etc.
