उत्तर
\[ \text{ Let x be the measure of each angle } . \]
\[\text{ Since, the sum of all the angles of a quadrilateral is } 360 °, \text{ we have: } \]
\[65° + 65° + x° + x° = 360° \]
\[ \Rightarrow 2x° + 130°= 360° \]
\[ \Rightarrow 2x° = 230° \]
\[ \Rightarrow x° = 115°\]
\[ \therefore \text{ The measure of each angle is } 115° .\]
