Answer:
x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.
Express in simplest a+bi form: Square root of 1b + Square root of -1b
Lets simplify 
We know 
We cannot simplify 
So a + ib form is
Im pretty sure it would be doubling the length of each side
