To find, the value of x = ?

We know that,

Consecutive angles are supplementary

The diagonals bisect the angles.

$2x\°+2(3x+7)\°=180\°$

Divided by 2 both sides, we get

⇒ $x\°+(3x+7)\°=90\°$

⇒ $x\°+3x+7\°=90\°$

⇒ $4x=90\°-7\°$

⇒ 4x = $83\°$

⇒ $x=\dfrac{83\°}{4}$

⇒ $x=20.75\°$

∴ The value of x = $20.75\°$

Thus, the required "option B) $20.75\°$ " is correct.
