Answer:
x = 25°
Step-by-step explanation:
Hello!
25° and x° are vertical angles, therefore they are equal to each other.
Vertical angles are angles formed by two intersecting lines that are non-adjacent.
The angle to the right of 80° would be 55°, because the sum of angles on a line is 180°.
Angle x would be 25° because the other straight line contains angles 80°, 50° and x°.
