Answer:
Step-by-step explanation:
Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)
