Answer 2

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°
