Q22:
<Please see attached file for the figure>
What is the value of x + y in the figure above?
(1) w = 95
(2) z = 125
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
(E. Statements (1) and (2) TOGETHER are NOT sufficient.
Hi, I would say E the two statements are not sufficient
The relationship between x,y,w and z can only be made if either of the lines were parallel. Which in this case are not.
(A)w =95, sure you might think 180-95=85 will give you the internal angle, but this is not sufficient to find x or way
B) z= 125 again you can calculate the internal angle 180-125 =55 again this is insufficient as there is no way to calcaulate C It is tempting to add the internal angles of w+z but it is not equal to x + y since there is no relationship, eg we dont know the sum of the angles, also the lines are not parrallel so we cannot use either of those rules.
D is insufficient
E is the correct answer.
