Find the values of the variables and the lengths of the sides of this kite.
Side A=y4, side B=x+5,side C= x+12, side D= 2x+5

D=C
2x+5=x+12
2xx+125
x=7
A=B
y4=x+5
y4=(7)+5
y4=12
y=12+4
y=16
A=y4==>164=12
B=x+5==>7+5=12
C=x+12==>7+12=19
D=2x+5==>2(7)+5=19
{a=12, b=12, c=19, d=19} 
thank you so much!!!!
