Question

In the figure, two identical regular hexagons are placed side by side as shown, then find the value of z.

• A. ${60}^0$
• B. ${90}^0$
• C. ${120}^0$
• D. ${160}^0$

Answer 1

The correct option is C ${120}^0$

Angle of regular hexagon$=120°$

So, $x=y=120°$

and $x+y+z=360°$

So, $z=360°-x-y$

$z=120°$

Hence option ${}^{\prime }{C}^{\prime }$ is the answer.
