Question

What is the measure of ARC JK?

Answer 1

You need this theorem: If a diameter of a circle is perpendicular to a chord of the circle, the diameter bisects the chords and its arcs.

Answer 2

90 degrees

Answer 3

Not 90. I'm drawing. Just a second.

Answer 4

Where you talking about the ark?

Answer 6

125 ?

Answer 7

Yes

Answer 8

What is the measure of ARC JK? This is the question I am helping with.

Answer 9

Yes, 125.

Answer 10

Oh, so that's how you figure arcs out? So 125 would be the answer?

Answer 11

That is how that particular arc is computed. 125 degrees is the measure of both arcs JK and JN

Answer 12

I saw that. Thank you. I get it now :)

Answer 13

Happy to help. Learn those theorems. :)
