Answer:
1) x=5 ;2) x=17 ;3) x=12 ;4) x=9 ;y =5.
Step-by-step explanation:
angle A =C
73=8y-7
A+B+C=180
73+73+6X+4=180
X=5
2) angleC=B
AC=AB
X+9=2X-8
X=17
3)angle A=B=C
so AB=AC=BC
let
ab=ac
5x-22=3x+2
x=12
4) LN=LM
so,
ANGLE L=M=N
equilateral triangle
so L=M=N=60
then,
7x-3=60
x=9
and, 11y-5=60
y=5.
