Answer 2

Step-by-step explanation:

we know that opposite side of a parallelogram is equal and parallel..

let us assume llgm ABCD

where A = 70 °

A + B = 180 ° ( linear pair )

B = 180° - 70°

B = 110°

since , B = D = 110° ( opposite angles of a llgm. )

we know that , sum of the angles of a quadrilateral

is 360°

A + B + C + D = 360°

70° + 110° + C + 110° = 360

C + 290° = 360

C = 70°
