PLEASE HELP! WILL NAME BRAINLIEST!!

Answer:
Y = 60 degrees and X = 12
Step-by-step explanation:
x+3 and 15 are congruent so x+3 = 15, 12+3 = 15 therefore x = 12
y = 60 vertically opposite angles are equal. :D
Answer:
x= 12
y= 60
Step-by-step explanation:
to find x we need to know that lines DC and AB are parallel, so they have the same length (I don't know if that is why they have the same length, but I know they do lol)
So you can make this equation and solve:
15=x+3
-3 -3
12=x
THEN, to find y angle A and C are vertical angles, so they are congruent (this is the reason why they have the same measure lol)
So, y=60 degrees :)
I hope this sorta helps lol :)
