AP is a secant. CP is a tangent. AP and CP intersect outside of circle O. Can you figure out the relationship that exists here? [br][br]Try using the lengths of the part of AP [i][b]outside[/b][/i] the circle and the [i][b]whole[/b][/i] length of AP, along with the part of PC [i][b]outside[/b][/i] of the circle and the [i][b]whole[/b][/i] length of PC. [br][br]What operations can be used with these values to make a true equation? [b]Also, take note that the values in the image are rounded to the tenths place, so any calculations you make will be approximate. [/b][br][br]Hint: For a tangent, the part [i][b]outside[/b][/i] the circle and the [i][b]whole[/b][/i] length will have the same value.

Did you figure out the relationship that exists? Here's a hint:[br][br][br][b]O[/b]utside x [b]W[/b]hole = [b]O[/b]utside x [b]W[/b]hole [br] [size=85][size=50](1st secant or tangent) [size=85][size=50](2nd secant or tangent)[/size][/size][/size][/size][br][br][br]or [b]OW OW[/b] for short[br]
