Question

two opposite angles of parallelogram are 5x-21 and X+75​

Answer 1

Answer:

since , we know opposite angle of parallelogram are qual !

so ,

5x-21 = x +75

5x-x = 75+21

4x = 96

x = 96/4

x = 24 ( ANS )

Answer 2

Since sum of opposite angles of a parallelogram is 180°

5x-21+x+75=180°

6x+54=180°

x+9=30

x=21°
