Question

If ABCD is a parallelogram and angle B =110 degrees,then angleA +angleC

Answer 1

the sum of angle a and c is 360-110-110=360-220=140

Answer 2

Hi ,

It is given that ABCD is a

parallelogram.

[ Sum of adjacent angles are

supplementary ]

= 180 - 110

= 70°
************************
We know that ,

Opposite angles are equal in a

parallelogram

***************************

<A = <C = 70°

<A + <C = 70 + 70 = 140°

I hope this helps you.
