Answer 2

Read through (especially theorem 4) of
http://www.regentsprep.org/regents/math/geometry/gp15/circleangles.htm

This will give you the central angle. What you need (x) is the supplement (i.e. subtract from 180\(^\circ\)) of the central angle.

Answer 3

110

Answer 4

not too fast...lol
Read carefully theorem 4 how to calculate correctly the central angle first. See if you can spot the error.

Answer 5

hmm...??

Answer 6

The central angle is half the sum of the two arcs, which gives you ?

Answer 7

55/

Answer 8

half the sum of the two arcs
= (1/2)(28+42)
= ?

Answer 9

35

Answer 10

Excellent, so x=?

Answer 11

35?

Answer 12

Please go back to the link and read up on theorem 4 to see what 35 degrees represent, and then reread the diagram of the question. You'll find the answer between the two.
