Answer 18

so for your exterior angles question, the reason is this: angle 10 = 180 - angle 11, and angle 9 = 180 - (180 - angle 11) = angle 11. Further, we have been given that angle 11 = angle 13, thus, we know that angle 9 = angle 11 = angle 13, and thus line c || line d. THis is the reasoning /proof of the "converse of the exterior angles theorem" ( http://hotmath.com/hotmath_help/topics/alternate-exterior-angles-theorem.html) . As to your second question, the answer is B i.e. arc RS = arc DF because the formula for arc length(lets call it 's') is, s = r * theta . In our case, the because angle DCF = angle RCS, the arc lengths are also equal.
