Patrick do you know the way how start this calculi ?

jhonyy9 (jhonyy9):

regular 11 sides polygon what mean ? how many degrees has the central angle of a triangle from this polygon ?

OpenStudy (patrickweewoos):

360/11?

jhonyy9 (jhonyy9):

like a first step divide 360 by 11 and will get the measure of the central angle of a triangle from this polygon - than you know this so you know that the sum of a angles measure of a triangle is equal 180 degrees - than you subtract from 180 this value of central angle will get the sum of the other two angles of a triangle ,what you know that these angles are congruent - the result what you get above divide by two and will get the measure of an angle

jhonyy9 (jhonyy9):

yes you are right

Patrick do you get the measure of the central angle of a triangle ?

OpenStudy (m.mahdi):

sorry I didn't check the 360 / 11 answer , thought the number Patrick said was its answer

jhonyy9 (jhonyy9):

no this not is right
