Please help, I really don't understand it.

**drwls**, Wednesday, April 2, 2008 at 10:02amIf one of the lengths goes to the center, where does the other one go? Is is a tangent? You don't say so. You talk about "between the tangents" but one of the lines is not a tangent.

**Reiny**, Wednesday, April 2, 2008 at 10:23amIf I understand the question, tangents are drawn to the circle from point P.

Let those contact points be A and B

In triangle APO,

AO=8.2

OP = 12.4

and the angle at A is 90º

let angle APO be ß

sin ß=8.2/12.4

ß = 41.4º

so the angle between the two tangents is 82.8º
