Answer 2

Answer:

30°

Step-by-step explanation:

As you can see line BC and AC have same length that means it is an isosceles triangle . So ,

angle ABC = angle ACB = 50°

According to question ;

50° + 50° + 2x + 20° = 180° ( angle sum property of triangle)

120° + 2x = 180°

2x = 180° - 120°

x = 60/2

x = 30°
