Answer:
option c - 9.9
Step-by-step explanation:
The angle between a tangent to a circle and the radius at the point of contact is 90 degree.
So the triangle is a right angle triangle.
The side opposite the 90°, is the hypotenuse.
Using Pythagoras theorem:
[tex]16.5^2 = 13.2^2 + x^2\\\\16.5^2 - 13.2^2 = x^2\\\\x^2 = 272.25 - 174.24 = 98.01\\\\x = \sqrt{98.01} = 9.9[/tex]
