11) the measure of each interior angle of a regular 11-sided polygon is

Step-by-step explanation:

Always , sum of exterior angle of any polygon  = 360

sum of exterior angle of 11- sided polygon  = 360

Measurement of  an exterior angle of 11-sided polygon  = 360/11

                                                 = 32.73

Measurement of  an interior angle of 11-sided polygon = 180 - 32 8/11

= 180 - 32.73= 147.27

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
