Please Help me Find NM using Secant

NM = 15

Step-by-step explanation:

There is a property of secants and tangents to a circle where:

The square of the tangent length is equal the length of the external segment of the secant times the whole secant length.

Therefore, in our question, we have that:

The values of NM, ML and MK are:

So we have:

So the length of NM is:

to rewrite a literal equation you may need to divide by a number, or by a variable.
