Plz help me and this is 7th grade math

I only know that Y equals 27

Step-by-step explanation:

because the side its Y

y= 27 and x= 63

Step-by-step explanation:

for y its is 27 because the other one is 27 and they are the same angle and x=  

63 because a straight line=180 and then there are two 27 angles and you add 27+27=54 then  that by 180 180-54=126 the divide it by 2=63 because there are two of that same angle

translate k to n and reflect across the line containing jk.
