$\qquad\qquad\huge\underline{{\sf Answer}}♨$

According to angle sum property of a quadrilateral, Sum of all angles of a quadrilateral measures 360°

So, let's solve for x ~

$\qquad \tt \dashrightarrow \:68 + 126 + 106 + x = 360$

$\qquad \tt \dashrightarrow \:300+ x = 360$

$\qquad \tt \dashrightarrow \:x = 360 - 300$

$\qquad \tt \dashrightarrow \:x = 60 \degree$
