Answer 3

intersection chords rule says that the product of the two pieces of each chord must be equal:



\[ab = cd\]

Answer 4

@whpalmer4 ok so what would i plug in for the equation?

Answer 5

take the two quantities on each chord and multiply them together. the product of the two segment lengths for the one chord must equal the product of the two segment lengths for the other chord.

I did label my diagram and provide the corresponding equation below the diagram...

Answer 6

you've got three numbers and an algebraic expression. two of the numbers get multiplied together, and the remaining number is multiplied with the expression. Those two products are set equal to each other, and then you solve for the value of the variable.
