Question

in a parallelogram abcd , angle c is 105 degree then angle d is​

Answer 1

Answer:

75 Degree because angle C and Angle D are co-interior Angles and sum of Co-interior angles is 180 Degree

Answer 2

Answer:

If you take diagram like this......

angle D = 75 degrees

Step-by-step explanation:

In parallelogram ABCD ,

Opposite angles are equal so if angle C = 105 degrees , Then it's opposite angle A will also be 105 degrees.

Sum of all angles of quadrilateral =360 degrees

A +B +C +D =360 degrees

angle D = angle B ( opposite angles )

let they be X degrees

=105 + x + 105 + x = 360 degrees

2x + 210 = 360 degrees

2x = 360-210

x = 150/2

x = 75 degrees

Hope it'll help you......
