14. Trick question, ignore the side.
Call the angle b.
34 + b + b = 180
2b = 146
b = 73
choice b
15. That's intersecting chords so the product of the segment lengths are equal:
5(22)=10 x
x = 5(22)/10 = 11
choice a
16. Intersecting tangent and secant;
[tex]x^2 = 5(19)[/tex]
[tex]x = \sqrt{95} \approx 9.75[/tex]
Choice a
