Help? New question for GEOMETRY

Sarla made a drawing of a geometric figure for a fabric print. The figure was a quadrilateral with a pair of angles measuring 40° each. If the figure she drew is a concave polygon, which of these could be the measures of the other two angles?

160°, 140°

220°, 110°

130°, 150°

200°, 80°

200º, 80º because concave meanse one angle would be larger than 180 and angles in a quadrilateral add up to 360.

Can you help me with this one?pleaseeee 
The figure shows two congruent regular polygons. 

 

What is the value of m? 

 252 

 108 

 72 

 144

144. You see, divide 360 by the number of sides and then double it to get that angle.
