Angle 3 and angle 1 are vertical angles. This means that they are equal to each other. Since angle 3 is 111 degrees that means that angle 1 is also 111 degrees
Angle 2 is adjacent to angle 3. This means that their sum is 180 degrees. With this knowledge you can make a formula like so (let angle 2 be x):
111 + x = 180
x = 69
Angle 2 is 69 degrees
Angle 4 and angle 2 are adjacent. Again, this means that they are equal to each other. Angle 4 is 69 degrees
