Answer:
AB=AC( ABC is a isosceles triangle)
Step-by-step explanation:
X+110=180(linear pair)
X=180-110
X=70
We know that sum of all 3 angle in triangle is 180
So
X+Y+40=180
70+40+Y=180
Y=180-110
Y=70
X=Y=70
Therefore it is a isosceles triangle

Step-by-step explanation:
A=40°
y=?
x=?
B=110°
so angle x=180-B
=180-110
=70°
now angle y
=40+x+y=180
=40+70+y=180
=110+y=180
y=180-110
y=70
I hope it helps
