We know that the diagonals of a square bisects it's angles and every angles of square are 90°.
The diagnol bisects the parallelogram in two equal parts.
The angle obtained are,
[tex]4x+17^{\circ}[/tex]
The sum of the angles are 90 deg.
[tex]4x+17+4x+17=90^{\circ}[/tex][tex]8x+34=90^{\circ}[/tex][tex]8x=56^{\circ}[/tex][tex]x=7^{\circ}[/tex]
Thus the value of x is 7 deg.
