Find the size of the final unknown interior angle in a polygon whose other interior angles are:

162°, 110°, 125°, 138°, 105° and 98°

Answer 1

Answer: the final interior angle is 162

Step-by-step explanation:

To find the sum of interior angles use the equation (n-2) · 180. Then add all of the interior angle together and subtract it from the sum of interior angles. There you would have your answer.

(n-2)·180= (7-2)·180= 5·180=900  

162+110+125+138+105+98=738

900-738=162
