Question

if one angle of parallelogram is 130 what is the sum of other

Answer 1

let the angles of parallelogram be = a,b,c,d
sum of angles of a parallelogram is = 360 
if angle a = 130 then (given)
then angle c will also be = 130 (opposite angles of parallelogram)
angle b = 180 - angle a 
angle b = 180-130
=50
angle d = 50 (opposite angles of parallelogram)

Answer 2

The sum of the angles of a parallelogram equals 360.
One angle is 130 so the sum of other angles are 360 - 180 = 180.
The other angles are 130 , 50 , 50 , 130.
