Answer:
115°
Step-by-step explanation:
The above shape is a quadrilateral.
A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.
The sum of interior angles of a Quadrilateral is 360°
Therefore,
115 + 65 + 65 + m = 360
245 + m = 360
m = 360 - 245
m = 115°
Therefore, m< B = 115°
