Question

I dont know where to begin to solve this with my kiddo

Answer 1

Since those are consecutive interior angles, we can conclude:

`\begin{gathered} 4x+6x=180 \\ _{\text{ }}add_{\text{ }}like_{\text{ }}terms\colon \\ 10x=180 \\ _{\text{ }}solve_{\text{ }}for_{\text{ }}x\colon \\ (10x)/(10)=(180)/(10) \\ x=18 \end{gathered}`

Answer:

18
