Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.

All four angles need to equal 360.

Subtract angle 1 and 3 from 360:

360 - 111 - 111 = 138

Angle 2 and 4 would also be identical, so divide the 138 by 2:

138 / 2 = 69

Angle 2 and angle 4 are both 69 degrees.

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

Hope this helped!
