Answer:
81
Step-by-step explanation:
Since angles B and D are opposite each other, they are supplementary.
The value of x is 81°, the correct option is B.
A circle is a round-shaped figure with all points lie in the same plane, the distance between all the points on the circle and the center of the circle is equal.
The line that passes through the center of the circle and has end point on the circumference is called the diameter, the radius is half the measure of the diameter.
A quadrilateral is a polygon with four sides, the quadrilateral are of many types like, trapezoid, parallelogram, rhombus, and square.
When a Quadrilateral is inscribed in a circle, the sum of the angles of the opposite sides of the quadrilateral is equal to 180 degree.
A quadrilateral ABCD is inscribed in a circle.
Angle B measures 121°.
Angle D measures (x - 22)°.
The both angles are supplementary
The equation formed will be
121 + (x -22) = 180°
(x -22) = 59°
x = 81°
