Answer:
A) y = 72 as opposite angles of ||gm are equal
2x=10 as opposite sides of ||gm are equal
x= 5
B)3x = 15 as diagonals of ||gm bisect each other
x =5
4y = 12 as diagonals of ||gm bisect each other
y =3
C) x= 54 as opposite angles of ||gm are equal
in triangle,ADC
x+ y +59 = 180 ( Angle sum property)
113+y=180
y = 180-113
y = 67
D) x =126 as opposite angles of ||gm are equal
angle 1 = 180 -126 (linear pair)
1 = 54
1+ y +90= 180 ( Angle sum property)
144+y=180
y = 180-144
y =36
Step-by-step explanation:
I hope you it helped you...
