{The sum of angle of opposite circumscribed quadrilateral in circle is 180°}
Answer:
In a cyclic Quadrilateral , sum of opposite pair of interior angles are Supplementary.
So, ∠A + ∠C=180°
And, ∠B + ∠D=180°
We have to find the value of x.
So, we will use the equation
∠B + ∠D=180°
→5 x +75° =180°
5 x= 180° - 75°
5 x= 105°
Dividing both side by , 5 we get
x=21°
