.Polygons and Quadrilaterals

So when we look at this two sides have similar angles there like the 61 degree and ther is anothe 61 degree so 61 + 61 = 122 

and we know all angles equal 360 degree's so 360 - 122 = 238  

and we see that there are also two angles that are a similar to another or congruent you could say so 238 divided by 2 = 119  

So x = 119 

Although I have given the answer I should have helped you find the answer rather than give it though keep in mind that all angles tally up  360 degrees that is an extremly important factor you seem to miss that will be vital to finding future answers
