Please Solve it fastly I have work​

Answer 1

Given quadrilateral ABCD is a ||gm.

In ||gm we have,

Opposite angles are equal

Sum of all angles is 360°

c = 50°

a + b + c + 50° = 360°

a + a + 50° + 50° = 360°

2a + 100° = 360°

2a = 260°

a = 130° = c

Answer 2

$\fbox{ANSWER}$

Angle C = 50° [opposite angles of parallelogram are of equal measure]

Angle B = 180°-50°=130°[The adjacent angles of parallelogram are supplementary]

Angle D=Angle B= 130° [opposite angles of parallelogram are of equal measure]
