Question

help!!!!!!!
Which equation could be used to solve for the measure of angle O

Answer 1

x + z = 180
x + y = 180
x - (y + z) = 360
x + y + z = 360

Answer 2

I believe its the first one

Answer 3

So why is w not in one of those equations?

Answer 4

Oh is the center of the circle is suppose to be N. That could help.

Answer 5

yes it is

Answer 6

That would mean a straight line with 180 degrees goes through the angles x and z.

Answer 7

so it x + z = 180

Answer 8

Yep.

Answer 9

thank you (:

Answer 10

do you have time for another question

Answer 11

Put it down.

Answer 12

What is the arc length of CD in the circle below

Answer 13

3.14 feet
4.88 feet
6.98 feet
11.78 feet

Answer 14

\[\text{ arclegnth}=\frac{n^o}{360^o} \cdot 2 \pi r \]
What is the angle there for the arc in question?
And what is the radius?

Answer 15

so would it look like 30/360 X 2(3.14)(6)

Answer 16

yes/

Answer 17

That answer should come out to be something nice because a lot of things will cancel.

Answer 18

I got 3.14

Answer 19

That is right. The answer is pi or approximately 3.14.
