Minor arc AC  = 2 * 65  =  130

And arc  ABC  =  360 - 130   = 230

And angle D   = (1/2) [ measure of arc ABC - measure of arc AC ] =

(1/2) [ 230 - 130 ]  =

(1/2) [ 100 ]  =

50°

15=-3(x-1)+9

15-9=-3(x-1)

6=-3x+3

6-3=-3x

3=-3x

3/-3=-3x/-3

-1=x

15=-3(x-1)+9

15=-3(-1-1)+9

15=3+3+9

15=6+9

15=15

so the answer is x=-1

Thank you so much, you've been really helpful to me a lot thanks! I appreciate it very much.

Let me prove this to you, NSS.....

Draw  DA

Then angle BDA  =  1/2  arc  BA   =  13.5°

And angle CAD  = 1/2 arc CD  =  24.5°

And angle x   is exterior to triangle DOA

And angle ODA = angle BDA 

And angle OAD = angle CAD

So by the exterior angle theorem......angle x  =

m

Um no i haven't it's math that I do... which is confusing at times

-2 times -3 is 6. The negative signs cancel each other out, and you are left with two times three, which is six. If you were doing a question like -2 times -5 times -3, the negative signs wouldn't cancel each other out, and you would get -30. The key do knowing whether you need a negative sign in your answer is this: if you have an even number of negative signs (0 included), your answer will be positive, and if you have an odd number of negative signs, your answer will be negative. When doing multiplication problems like these, 1. Find out if your answer will be negative or positive, 2. Multiply like normal, and 3. Write your answer down (don't forget the negative sign, if it is needed!)

Hope that helps you!

x=-1

The measure of the angle formed by 2 chords  that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs.

So  x   =  (1/2)( measure of arc AB + the measure of arc  CD )  =

(1/2) ( 27 + 49)  =

(1/2) ( 76)  =

38°

you don't type it. In the corner of the calculator there will be a button that says 2nd. Click that and there will be a button called asin. that is sin^-1

sin 3x  =

sin (2x + x)  =

sin2xcosx + sinxcos2x =

2sinxcosxcosx + sinx (2cos^2x - 1) =

2sinxcos^2x + 2sinxcos^2x -  sinx =

4sinxcos^2x - sinx 

sinx ( 4cos^2x - 1 )

Note......other answers are possible....!!!

Oohhh now that stuff is good!
