Question

in a ||gm if A=115° then find B C D

Answer 1

1) a=c = 115 , a+c = 2*115
2) b=d = (360-2*115)/2
reason 1) opposite angles of a parallelogram are equal
2) sum of angles of a quadrilateral is 360 degree

Answer 2

\[A=C=115 and B=D=x\]
Total angle 360
A+B+C+D=360
115+x+115+x=360
2x+230=360
2x=130
x=65
