Question

and is a quadrilateral in which an 11 DC and AD 11 BC. find Angleb,angle c and angled
d
​

Answer 1

Step-by-step explanation:

In quadrilateral,

<A = 50°

<A =<C( vertically opposite angle)

<C = 50°

Now,

<A + <B = 180°

50° + x = 180°

x = 180° - 50°

<B = 130°

now,

<B = <D(vertically opposite angle)

<D = 130°

Answer 2

Answer:

Angle C is 50 degree

Angle D is 130 degree

Step-by-step explanation:

Since AD || BC and AB || CB

ABCD is a parallelogram

Angle A = Angle C ( Opposite angles of llgm are equal)

Angle C = 50 degree

Similarly, Angle D = Angle B

D + B = 360 - ( A+B)

D + B = 260

2D = 260

D = 130
