Question

use the diagrams to answer the following questions Number 7

Answer 1

To solve this we going to need the Tangent-Secant Interior Angle Theorem

Works in the following way

Using that formula we get

$\begin{gathered} \beta=\frac{x}{2} \\ \\ 2\beta=x \\ \\ x=2*35\degree \\ x=70\degree \end{gathered}$

Answer: x=70°
