Answer 1

Angle BOD = 2(Angle BAD)
(inscribed angle theorem)

y = 2(50°)
y = 100°

Quadrilateral ABCD is a cyclic quadrilateral.
Therefore, Angle B + Angle A = 180°
x+50° = 180°
x = 180°-50°
x = 130°

Hence, $x=130°, y=100°$

Answer 2

Answer:

y=2*50

=100

Step-by-step explanation:

x+50=180

x=30
