Answer 2

Answer 3

using the same rule as in previous question, you get
43 = (43+JK)/2
can you find JK from here ?

Answer 4

@hartnn do you do 43 divided by 2?

Answer 5

43 = (43+JK)/2
first, multiply by 2 on both sides.

Answer 6

@hartnn okay I got 86

Answer 7

you got 86 = 43 +JK
now subtract 43 from both sides, and you'll get JK =...?

Answer 8

Isn't the measure of arc JK simply the same as the measure of the central anlge that interceps arc JK? Just like arc MN has the measure of 43, the same as its central angle.

Answer 9

I got 43

Answer 10

yeah! @mathstudent55 :)

Answer 11

@hartnn

Answer 12

43 is correct.

Answer 13

is 43 JK?

Answer 14

to be able to say central, centre should be given...JK=43 is correct :)

Answer 15

thank you!!!!

Answer 16

welcome ^_^

Answer 17

We know L must be the center because m(arc)MN = 43 and m<MLN = 43.
