As AB=AC hence ∠B=∠C (Equal sides AB=AC have equal opposite angles)
Using theorem, Sum of interior angles of a triangle is 180
o
.
Therefore ∠A+∠B+∠C=180
o
⇒110
o
+2∠B=180
o
[GIven ∠A=110
o
]
⇒∠B=35
o
Hence, ∠B=∠C=35

x = 35°
Step-by-step explanation:
By angle sum property,
110° + x + x = 180°
2x = 70°
x = 35°
