The sketch of the question is given below

Using the principle:

Then


9x+25=2*(4x+17)

Simplifying the expression


\begin{gathered} 9x+25=8x+34 \\ \text{collect like terms} \\ 9x-8x=34-25 \\ x=9 \end{gathered}

The value of

In circle C, the inscribed angle DEF measures (4x + 17)" and DF measures (9x-example-1
