Question 113625: I do not have any clue what to do with this problem.
Here it is:
Solving oblique triangles using the law of cosines.
You have a triangle with 3 sides. It looks like this description: angle F is at the top, angle E is to the bottom right, and to the left of it is angle D.
between F and E it is 140. between E and D it is 156. between D and F is 96.
The question is: "Find the size of angle F in oblique triangle DEF.
I hope this is descriptive enough for you to help me because I honestly have no clue what to do. I don't understand the law of cosines and the Law of Sines either.

Question 113927: I hope this is in the right section, please forgive me if it isn't!

My directions are: Find the measure of an angle betwen 0 degrees and 360 degrees coterminal with each given angle.

One of my problems is: 482 degrees

Now, I missed half the notes my teacher had on this lesson because I was checked out of class, but I remember her saying something about subtracting or adding 360 degrees to find the answer? But I'm not completely sure.

Well, for this problem I subtracted 360 degrees from 482 and got 122 degrees. Is that the coterminal then? or is there something else I must do? When would I have to add 360 degrees?

Can someone help me with this please? Thanks in advance!

Question 118669: Hello,
I am a freshman student having problems in goemetry. It would be wonderful if I could have a little extra help on a few problems. I would greatly appreciate it. :) Here is my first problem.
A calculation shows that an angle has a measure of 113.05 degrees.
This angle can be written in the form A B', measured in degrees and minutes.
What is the sum of A and B?

Note: In the second sentence the A has a degree symbol after it.

This is how far I got into the problem. 113 + ?/60 + ?/ 3600
