Explanation

We are given the following:

We are required to determine the value of y in the figure given.

We know that vertically opposite angles are equal.

Therefore, we have:


\begin{gathered} (3y+20)\degree=(2y+30)\degree \\ 3y+20\operatorname{\degree}=2y+30\operatorname{\degree} \\ 3y-2y=30\degree-20\degree \\ y=10\degree \end{gathered}

Hence, the answer is:


y=10\operatorname{\degree}

Option D is correct.
