Because we know the chord RS and chord ST are equal, which of the following is true?

• RT is = 180

• Minor arc RS is congruent to minor arc ST

• Minor arc RS is half of minor arc ST

• Minor arc RS is the same degree as the major arc RST

What is true about the following image?

• Chords FG and HG are congruent

What do you know about line segments AB and CD

• They are both chords

• They are both secants

• They are congruent because their minor arcs are congruent

• They add to 360

What is the first thing you would do to solve for x?

• 127 = 5x

• 5x = 3x + 6

• 360 - 127 -127 = x

• 5x + 3x + 6 = 180

Find x.
