Question

Question below!!!

Answer 1

@calculusfunctions

Answer 2

idk if thats a right angle or not.

Answer 3

Yes, ∠BAC is a right angle.

Answer 4

I'd think so, it's, AC looks to me like a tangent

Answer 5

Tell me if you know how to proceed now.

Answer 6

so would i just subtract 34 from 90?

Answer 7

No.

Answer 8

im stumped.

Answer 9

OK, first draw the line segment OY. Now, if the measure of arc BY is 34°, then that implies only that the central angle ∠BOY is 34°.

Answer 10

yes.

Answer 11

Do recall what I said in the previous example?

Answer 12

id have to go back. :/

Answer 13

Its 68 isnt it?

Answer 14

The central angle is twice the inscribed angle, or the inscribed angle is half the central angle, iff both the inscribed angle and the central angle are subtended by the same arc.

Answer 15

NO.

Answer 16

im sorry. hard time understanding

Answer 17

jow, i think thats the wrong oicture.

Answer 18

mine looks different...

Answer 19

jdoe*

Answer 20

unfortunately, no, you see when they labeled that angle BY as 34 degrees, they really meant as calculusfunctions said, a CENTRAL ANGLE, as opposed to the angle from the vertex way down there

but 34 degrees from the center of the circle

Answer 21

@chickennuggetsaregood do you notice that the central angle ∠BOY and the inscribed angle ∠BAY are both subtended by arc BY?

Answer 22

yes...

Answer 23

OK so then if ∠BOY is 34°, then what must be the measure of ∠BAY?

Answer 24

@chickennuggetsaregood ??

Answer 25

im super confused...

Answer 26

Where? Do you not understand the theorem or is it something else. You need to be more specific.

Answer 27

This implies that arc BC is 107°. One of the properties, is that an inscribed angle is exactly one-half of the central angle iff both the inscribed angle and the central angle are subtended by the same arc. If you observe, you notice that the inscribed angle ∠CAB and the central angle

Answer 28

∠BOY = 34° is the central angle, correct?

Answer 29

yes..

Answer 30

wouldit be half of 34?
