Question

Help please , is this just simply 32 or do I do 360-32

Answer 1

Neither

It's number 2 on this page: http://www.regentsprep.org/regents/math/geometry/gp15/circleangles.htm

So the arc YZ is twice the angle x.

Answer 2

So would it be 1/2*32

Answer 3

Because that is the formula

Answer 4

16

Answer 5

is what i got

Answer 6

Iss that the correct answer

Answer 9

Read this again

"the arc YZ is twice the angle X."

Answer 10

Answer 11

No it is not 16.

Answer 12

ohh 32 times 2

Answer 13

because x is 32 right

Answer 14

Yes.

Answer 15

Okay thanks

Answer 16

So just as you said, this would be 21 * 2

Answer 17

42

Answer 18

Yes, that would be BC.

But the question doesn't ask for BC.

Answer 19

yes

Answer 20

42+21

Answer 21

63 is what i got

Answer 22

The question asks for arc BAC.

Answer 23

Well if we already have 21 and BC would be 21 * 2 The total is 42+21???

Answer 24

You've done a question just like this already...

Answer 25

OMG , yes bur we need BAC

the second question you posted here is like this.

Answer 27

You have BC and you need BAC.

Answer 28

21

Answer 29

Okay well 42 is BC right?

Answer 30

Yes, BC is 42. Now use the same logic you used in that question i just posted (the 2nd one)

Answer 31

So in that question, i subtracted 99 from 36,, which means I would need to do 360-21

Answer 32

360*

Answer 33

No.

You already know that arc BC is 42. You need arc BAC.

Answer 34

Well the 21 has to come into play

Answer 35

It already did.

Answer 36

BA is 21 right

Answer 37

"You already know that arc BC is 42. You need arc BAC."

Answer 38

I don't know how to get A

Answer 39

What is A???

You have arc BC and arc BAC. Those two together make a whole circle. You know how many degrees there are in a circle. You know what arc BC is.

Answer 40

360-42

Answer 41

Much better.

Answer 42
