Question

Arc AB=127
Arc BC=127
how to get measure of angle ACD

Answer 1

i am assuming dc is a tangent to the circle. is that correct?

Answer 2

I believe so

Answer 3

so arcs ab=bc=127
so they addd up to what?

Answer 4

ive asked severl ttimes and ive been told its not possible to solve so if being tangent is the way to go then i think so 254

Answer 5

is the triangle supposed to be touching the circle at c? If so it is totally possible to solve this and solve it easily!

Answer 6

yes sorry would ti help to post the link

Answer 7

yes

Answer 8

if you post it I will help you solve this easily

Answer 10

dont mind the letter given in the drawing

Answer 11

what is the arc lenght of an entire circle? any circle.

Answer 12

360

Answer 13

so you have ab=bc=254. so what is the measure of arc ac?

Answer 14

sorry that is ab+bc=254

Answer 15

127

Answer 16

no. ac =360-254. Do you understand that?

Answer 17

yes

Answer 18

so ac=106.
here is a theorem that you definitely learned and need to remember:

1/2 arc ac= angle acd

Answer 19

ok so acd comes to53

Answer 20

correct.
do you want a link to an online text for the theorem?

Answer 21
