Angle 2 and Angle 7 are interior angles.
We know, they add up to 180 degrees.
From the figure, we can write:
[tex]\angle2+\angle7=180\degree[/tex]
We know ∠2 = 36°, so,
[tex]\begin{gathered} \angle2+\angle7=180\degree \\ 36\degree+\angle7=180\degree \\ \angle7=180-36 \\ \angle7=144\degree \end{gathered}[/tex]
The 'last choice' is right.
So,
Answer[tex]\angle7=144\degree[/tex]
