Answer 1

Answer:

x=5°. y=92/7°

Step-by-step explanation:

ABCD IS a ||gm

AB||CD, BD is a transversal

therefore angle CDB = angle DBA=60°

DBA=12x

12x =60

x=5

AD||BC, BC is a transversal

angle DAB + angle CBA =180°(co- interior angles)

28°+angle DBA + angle DBC=180°(DAB = 28°)

28°+60°+7y=180°

88°+7y=180°

7y=92°

y= (92/7)°

Answer 2

Answer:

we know that in parallelogram opposite angles ar equal

that's means 12x+7y = 28+60

and their is a diagonal

12x = 60

x= 60/12= 5

7y= 28

y= 28/7

y=4
