Question

What is the length of JK explain your reasoning

Answer 1

kj =
`(mj(mn+mj))/(lk + kj)`

Explanation:

The product of the length of one secant segment and the length of its external secant segment is equal to the product of the length of the other secant segment and the length of it external secant segment.

kj(lk + kj) = mj(nm + mj)

kj =
`(mj(mn + mj))/(lk + kj)`
