It can be viewed as a pair of congruent triangles with a common base.
It has 2 diagonals that intersect each other at right angles.
The longer or main diagonal bisects the other diagonal.
A kite is symmetrical about its main diagonal.
Now,
[tex]\begin{gathered} x=\frac{360-52-86}{2} \\ x=111 \end{gathered}[/tex]The answer is x = 111°
