I think <2 would be 45 degrees. <1 is 135 degrees so that means that 4 would be supplementary to angle one. Supplementary angles added together equal 180 degrees. So, you would have to subtract 180-135 leaving you with 45 degrees. This means that 4 would be 45 degrees. Two is vertical to four so it means that they equal the same amount. That means that <2 is 45 degrees.
