Answer:
<h2>MN = 9.1 cm</h2>Step-by-step explanation:
If MN is tangent of a circle then the angle M is a right angle.
We have a dimeter of acircle d = 8 cm.
Therefore the radius CM = 8 cm : 2 = 4cm.
In a right triangle CMN use the Pythagorean theorem:
Substitute CM = 4cm and CN = 9.9 cm:
<em>subtract 16 from both sides</em>
