Problem 44. I tried, truly lost on this one.
I did that because the arc looked like a half of the circle because AC is a diameter in the circle.How did you get 316/2 = 92.94??
I would consider how the desired angle, ACD, is related to the known arc, DCA. Do you see how arc AD is related to each?
Here is a hint when you ask for help: rather than just show a calculation, it's a lot more useful to say in words what you are thinking. Then we can tell whether you just wrote the wrong number, or had an entirely wrong idea.
I presume you do know those circle theorems to which I gave you a reference in some thread; one of those is presumably what you have in mind here.

I don't know which to use, is it the 4th one?How did you get 316/2 = 92.94??

Arc AC is half a circle; but that is not what they are asking about.
Do you understand that arc DCA is the long arc that starts at D, passes through C, and ends at A?
Yes I do, I feel like I am getting no where. Is the answer C since 1/3(100) = 66.66 repeating?

No, there is no intersection of two chords. All you need is #1.
Don't miss the fact that B is the center of the circle.
But first, can you answer my questions? They were meant to help you along, so if you can answer even one part, it will give us more to talk about. The important thing is to think -- get moving, try something, and you will have things to think about and learn from. Don't wait until you know just what to do.
You really need to stop using a calculator. Otherwise you will keep saying things like 316/2 = 92.94. There are many things I can say about that. First of all 316 is even so when divided by 2 there will be no decimals. 2ndly, 316 is more than 300. It is even much more than 200. If you divide 200 by 2 you get more than 92.94, so how are you dividing 316 by 2 and only getting 92.94. I myself make arithmetic mistakes all the time but I catch almost all of them because I think and realize my result does not make sense. If you use a machine to do your calculation you will make many more mistakes then doing the problem by hand or in your head. Why? Because you type in numbers and might miss one digit or type it in wrong and get the wrong answer. The other reason not to use electronics is that it makes math boring and more difficult.Yes I do, I feel like I am getting no where. Is the answer C since 1/3(100) = 66.66 repeating?

44. 360-316MISTER Happiness, you're told that arcDCA = 316 degrees:
that means that if you start from D and go CLOCKWISE,
you will go through C then continue to A; you've now
travelled 316 degrees.
So if you continue from A to starting point D,
how many degrees will you travel?
