I would say the answer is A. 65
Since angel A is 35 degrees, and angle c is a right angle which is 90 degrees, I would probably say that angle B is 65 degrees.
Hope this helped! :D

The answer is 74. 518 has 8 in it and 74 has 4 in it. 4 goes in 8 so you know that they can go together.
Line B is incorrect cause he did not do like terms
