Answer:
(C)x=11.6, y=23.2
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent
Applying this theorem in the diagram, we have:


Next, we apply Theorem of Intersecting Chords
PV X VQ=SV X VR
4 X x= 2 X y
Recall earlier we got: x=11.6
2y=4 X 11.6
2y=46.4
Divide both sides by 2
y=46.4/2=23.2
Therefore: x=11.6, y=23.2
The answer would be in fractions 7 over 250
The answer to the first part of your question is 9
as for the second part 36/4 (which is 9 btw) then subtract 2 I answered this one the best I could (let me know if I'm wrong)
(i just don't have to much time on my hands because I have homework myself)
