  Read the following SAT test question, then click on a button to select your answer.

  In the figure above, x = 60 and y = 40. If the dashed lines bisect the angles with measures of x° and y°, what is the value of z?

  A.25

  B.35

  C.40

  D.45

  E.50

  Correct Answer: E

  Here"s Why:

  First, add the labeled points A, B, C, D, E, and O to the figure, as shown above. Then segment

  bisects

  AOC, so m

  AOB = m

  BOC, and m

  AOB + m

  BOC = x° = 60°. Thus, m

  AOB = m

  BOC = 30°. Similarly, m

  COD = m

  DOE = 20°, because

  COD and

  DOE are of equal measure and the sum of their measures is y° = 40°. From the figure, it follows that z° = m
