Angles at a point add up to 360&deg;. A reflex angle is greater than 180&deg;.<br><br>
&bull; Read the given acute/obtuse angle from the diagram<br>
&bull; Angle s is a reflex angle<br>
&bull; Angle s = 360&deg; − given smaller angle<br>
&bull; Angle s = 360&deg; − 175&deg; = 185&deg;<br><br>
Final Answer: 185
