ANSWER


44 \degree


Step-by-step explanation

The sum of the exterior angles of a polygon is

360 \degree


So we sum all the exterior angles to obtain,


\: < \: DEG +61 + 88 + 52 + 115 = 360


This implies that,


\: < \: DEG + 316 = 360


We group like terms to obtain,


\: < \: DEG = 360 - 316

This simplifies to,


\: < \: DEG = 44 \degree


Therefore the correct answer is option B.
