Question 58: A bisector cuts something into two equals halfs. Since <ABD is 65.2, you have to multiply it by two to receive your final answer of 130.4.
Question 59: A right angle is equal to 90 degrees. So 90 split into two is 45. you take the 45 and plug it into the equation: 45 = (2x + 3) to find your answer.
45 = 2x + 3
42 = 2x
21 = x
