Answer:
2 is 60 degrees, 5 is 90 degrees, 4 is 20 degrees, 3 is 30 degrees, and 1 is 90 degrees.
Explanation:
All angles have to equal up to 90 degrees. Some you can guess, but others you might have to think about. So just look at the lines and you will see four boxes or four sections. Each have to equal up to 90 degrees, so that's what you get for those. It's kinda hard to explain, but I hope this helps, have a good day. c;
