question 2
I think angle a is 57 degrees because on a straight line there is 180 degrees and so you need to add 68 onto112 degrees to make it 180 and 35 degrees is on a right angle so you need to add 55 degrees to make it 90 degrees. Then you add 55 and 68 to make 123 degrees and 57 add 123 is 180 and it is in a triangle which has to have 180 degrees and there is so I think it is 57 degrees.
