I have no idea how to do 10.

What you need to do is find the slopes of the two sides and then it should be pretty easy from there

That is what I did and I believe that is what we talked about in class but I could be wrong

I don't get how to do number 16 b

I see how to do the slope thing, but not finding the center.

You have the positions of O and K, and they're on the same y-position, therefore the distance between them is the difference of the x-positions. Because O is the center and K is a point on the circle, OK is a radius.

How would you solve problem 8. I am having a hard time with it. Any suggestions?

Thanks,

Ben

I think for #10 the midpoint formula

would work.

Colin Reeder

It's not a midpoint, unless a midpoint can be between three points somehow...

Lindsey Habig

No, just between points D and F because DF is the diameter because it goes through Q, which is the center

of the circle.

On #8,

and we learned today that you can take half of the

arc's measure and that will be the inscribed angle's

measure. To find arc BC, you would take arc BA, which

is given, and subtract it from CA.

Hope this helps.

Please help!

Does anyone know how to solve #14 after you get

vertical angles congruent? Do you have to get one of the other

angles congruent? If so, which ones and how?
