(1) Angles of the quadrilateral are 90º, 90º, x, and y, where x + y = 180º. Clearly, x and y can take any values so that they add to 180. So, we don't get a unique answer. Hence, (1) is NOT SUFFICIENT. (2) http://s1.postimage.org/2sx39t43o/Quadrilateral.jpg x + 2x + a + d = 360º Again, we don't...

(1) z > x implies side opposite to angle z > side opposite to angle x. So, AC > AB or AB < AC(since side opposite to angle z is AC and side opposite to angle x is AB). Answer to the main question is "no". So, (1) is SUFFICIENT. (2) AC > AD does not imply whether AB < AC or AB > AC. So, (2...

In the rectangular coordinate system, line k has equation y = mx + b, where m and b are constants. does the line k intersect quadrant II? 1) Slope of k is -1/6 2) The y-intercept of k is -6 One thing people miss about this question is that a line stretches infinitely in both directions - if a quest...

YES...! Absolutely correct....!ankurmit wrote:I think answer should be C only
As in 2nd stem we are given that angle ABC is twice the measure of angle BCD.
Hence possible values are only 90,90,120,60.
but MOST SURPRIZING element in this ques is ...
ACC TO GMAC , ANSWER IS E...!

also think that the answer is E possible angles of rectangle are 90,90,120,60 the answer is yes 45,90,90 135, the answer is no GUYS... in second scenario ie 45, 90 , 90 and 135 -> WRONG SCENARIO because 135 is not the double of 45 (as 2nd statement says) so there is only one scenario exists and tha...

the answer should be E here's why st(1) says two angle are 90` but the remaining two angles could by anything to make 180` like x+y=180`Not Sufficient st(2) says one angle is twice the other, also Not Sufficient because we know only relationship of these angles but not have information about the ot...
