In the figure, ABCDEF is a regular hexagon with side 1cm. What is the area of triangle BDX?

A. AF = FX

B. \(\angle AFX\) = \(\angle XFE\)

Are we supposed to find the actual area....NOSo what should be sufficient here..

INCASE the triangle formed is unique, our answer is YES..

Statement I gives the size of FX as 1

But it could be anywhere on the arc of 1 cm from F..

Insufficient

Statement II gives the angle AFX and XFE to be equal..

This tells us that x is on a line equidistant from B and D..

Do we know the line where x exists but not the distance from F..

Insufficient..

Combined..

We can draw the triangle as we know exact position of all three vertices X, B and D...

Sufficient
