Question

Can someone please help me in this assignment I really don't know how to do it

Answer 1

The angles PBC and PBA are supplementary, then it sums 180, so we have the next equation

`\begin{gathered} 5k+12+83=180 \\ 5k=180-83-12 \\ 5k=85 \\ k=(85)/(5) \\ k=17 \end{gathered}`

Then, the answer is C.17
