Question

The radius of circle Y is 34, AB=60 and the measure of arc AC is 71 degrees. Find the measure of YD and DC. (Diagram drawn)

Answer 1

Help?

Answer 2

How'd you get that?

Answer 3

find YD using right angled triangle

Answer 4

Use Pythagoras theorem

Answer 5

could you show work please and thank you?

Answer 6

because i tried that but how'd you find AY?

Answer 7

that's the part I don't get

Answer 8

r^2 = (30)^2 + YD^2 r=34

AY= 60/2 (radius is perpendicular bisector to any chord)

Answer 9

Yes, but wouldn't AD equal 30?.. not AY

Answer 10

sorry AD.
AY = radius

Answer 11

ok... I think I get it now

Answer 12

Could you wait one second while I work on it to make sure I got it?

Answer 13

Ok

Answer 14

but wait.. how'd you solve for r... u had two variables, I'm sorry for asking all these questions

Answer 15

c'mon miss u hv the radius = 34 (check ques)
