Given that the other angle values are single-digit integers, the most reasonable interpretation for "2/" in this context is the integer 2. The slash is likely an extraneous mark or a stylistic way o

Step 1: Identify the numbers indicated in the angles of the polygon.
The numbers clearly marked inside the angle arcs are 5, 3, 2, and 2. There is also a mark "2/" near the bottom vertex, which represents the fifth angle of the pentagon.

Step 2: Interpret the ambiguous mark "2/".
Given that the other angle values are single-digit integers, the most reasonable interpretation for "2/" in this context is the integer 2. The slash is likely an extraneous mark or a stylistic way of writing the number.

Step 3: Calculate the sum of all identified angle values.
The angle values are $5, 3, 2, 2,$ and 2.
