Question

What is the answer to this im having trouble figuring it out

Answer 1

option c - 9.9

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:

`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 = √(98.01) = 9.9`

Answer 2

I think it’s 9.3 hope that helps
