Answer 1

Okay...so what equation do you have so far? (that is...if you've started it)

Answer 2

I have no idea what to do

The lesson notes don't really tell me anything helpful

Answer 4

Well fudge sticks. What DO the notes say that might be at least a tinge bit helpful?

Answer 5

anything?????

Answer 6

umm....

Theorem 7-13 The measure of the angle formed by two secants intersecting outside the circle equals half the difference of the intercepted arcs.



Theorem 7-14 The measure of the angle formed by a tangent ray and a secant ray intersecting outside the circle is equal to half the difference of the intercepted arcs.



Theorem 7-15 The measure of the angle formed by two tangent rays intersecting outside the circle is half the difference of the intercepted arcs.

Answer 7

it give examples for each but i would have to write it in the equation thing

Answer 8

oml *face palm*

Answer 9

sorry xD

Answer 10

ill try to print screen it hold on

Answer 11

Alright so, that wont work

Answer 12

give me a few minutes

Answer 13

GOT IT

Answer 14

ermmm ok

Answer 15

you need to "understand" what this means

Theorem 7-13 The measure of the angle formed by two secants intersecting outside the circle equals half the difference of the intercepted arcs.

Answer 16

It's hard for me to understand that for some reason

Answer 17

two secants intersecting outside the circle

that is what you have. Do you see two lines that meet out side the circle
(and they form an angle)

Answer 18

Oh yeah I see that

Answer 19

now
** half the difference of the intercepted arcs.***

"intercepted arc" are the "arcs" between the two lines.
they tell you the size of one of the arcs. do you see it? what size is it ?

Answer 20

No I don't see it
