A formula will help us here

The formula states that the sum of the faces and vertices will be two more than the number of edges.

From there, we can substitute in our values;

(16) + (14) = E + 2

And we can solve.

30 = E + 2

Since this answer is two more than the amount of edges, we can subtract by two in order to solve.

28 = E

Therefore there are 28 edges in our figure.

Hope this helps!

i think it might be a but you might want a second opinion
