QUESTION 8

We can edit the image as follows:

Recall: The Tangent-Chord Theorem states that the angle formed between a chord and a tangent line to a circle is equal to the inscribed angle on the other side of the chord. That is why we have x where it is.

Note that the angle subtended by a chord to the center of a circle is twice the angle at the circumference.

The angle subtended by the chord to the center is gotten by:

`\Rightarrow360-165=195`

Therefore, we have that:

`\begin{gathered} x=(195)/(2) \\ x=97.5\degree \end{gathered}`
