**Answer:**

115°

**Step-by-step explanation:**

The above shape is a **quadri****lateral****.**

**A**** ****quadri****lateral**** **is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The sum of **interi****or**** **angles of a **Quadri****lateral** is 360°

Therefore,

115 + 65 + 65 + m = 360

245 + m = 360

m = 360 - 245

m = 115°

Therefore, m< B = 115°
