Answer:
x= 60°
Step-by-step explanation:
Since AB=BC, this is a isoscleses triangle. According to property, 2 angles of an isoscleses triangle are equal. So,
∠B=∠C
∠B and ∠120° are Angles on the same line, which means their sum=180°
By this, we find the ∠B= 60°
∠C is also 60°
Now, we use Angle sum property of triangle,
60°+60°+ x = 180°
120°+ x= 180°
x= 180°-120°
x= 60°
