do you first add the degrees up then divide by 2?

5. SmokeysTheName

yes im pretty sure, but lemme get someone on this question to verify.. @hartnn

6. Mertsj

The angle formed by two intersecting chords is 1/2 the sum of the intercepted arcs.

7. needmathhelp7

okay @SmokeysTheName :)

8. needmathhelp7

@Mertsj yeah! so then what do you do?

10. phi

The measure of an angle formed by 2 chords = 1/2 the sum of the measures of the intercepted arcs.

okay I was right then good! :)

12. hartnn

yes, so your thought 'do you first add the degrees up then divide by 2' is correct.

13. needmathhelp7

so i added them up and got 124..then divided 124 by 2 and the answer is 62? :)

14. SmokeysTheName

yes thats right (:
