x=96


all interior angles equal 180


Subtract exterior andgles by 180 to get interior angles because they are supplementary

180-134=46

180-130=50


Get the third angle inside the triangle

180-50-46=84


subtract by 180 to get x because they are supplementary

180-84=96


Therefore x =96

Triss [41]
We know that

<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]

</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²

the answer is
1390.5 cm²
