1. Polygons with 4 sides add up to 360°.

So add up the sum of the interior angles which is: 115+103+53=266.

360-266=94°. Your answer to 1 is 94°.

2.The formula to find the sum of the interior angles in a polygon is 180×(n-2) n being the number of sides of the polygon.

180×(5-2)=540°.

540-318=222

As both missing angles are equal you just half 222 which is 111°.

3.90+90+51=231

360-231=129°.

4.108+124+107+98=437°.

540-437=103°.

5.180×(6-2)=720°

119+137+113+104+118=591°

720-591=129°
