Answer:
x = 105°
Explanation:
chords that are equidistant from the centre are congruent.
since the chords are congruent the arcs that subtend them are both congruent, in this case both x
the sum of the arcs in a circle = 360° , then
2x + 42° + 108° = 360°
2x + 150° = 360° ( subtract 150° from both sides )
2x = 210° ( divide both sides by 2 )
x = 105°
