If PT = 5.3, TU = 3.8, and UV = 6.4. Solve for the measure of VS and round to the nearest hundredth.

Can someone please help me with this, usually I'm really good at math...
I even tutor but this, I don't get!!! :(
 
Look for "secant-tangent theorem"

SV² = PV * UV
SV² = (5.3 + 3.8 + 6.4) * 6.4
SV² = 15.5 * 6.4
SV² = 99.2
SV = ?99.2
SV = 9.96

I sure don't "get" it either, Amanda!
On VS : what/where d'heck is "S"?
Plus these 3 chords can be made to fit any circle with diameter > 6.4
What am I missing?

To Aladdin: WHERE did you get that?
 
Your statement of the problem is unclear.
A segment of a circle is a specific term; it means the region cut off by a chord of a circle. It has an area.
Do you mean chords? or tangents? or secants?
These are all segments that relate to circles.

I agree with Denis: where is S?
 
WHY do you think that's the answer?
If it is, it is the answer to WHAT?
