Answer:
x=12 y=6 m(ABC)=102 m(BCD)=78 m(DAB)=78
Step-by-step explanation:
alright mate so lets start with the properties of parallelogram:
- Opposite angles are equal
- Sum of any two adjacent angles is 180degree
(there are more but we will use those here)
- so lets start with 1st property for help:
m(BCD) is opposite angle for m(DAB) so those equations should be equal each other and this will give us a hint
i just changed the places of x to be in one place and s same for y then divided both sides by 2
- Now lets use the 2nd property (sum of two adjacent angles is 180)
m(ABC) is adjacent to m(BCD) so
add x to x and y to y it will be
- Now we going to use the first one x=2y in this equation so we can deal with one variable
replace x with 2y so 11x will be 22y
added the y to y and then divided both sides by 30
now we got x and y
then lets start to substitute every x and y in the equations

now we got everthing hope i helped you sorry also for being late it toook alot to type it so you can understand
