Question

Angle depicted by above figure is.

• A. ${360}^{\circ }$
• B. ${720}^{\circ }$
• C. ${540}^{\circ }$

Answer 1

The correct option is B ${720}^{\circ }$

As per the given figure, ray makes two complete rotations (as we can see two spirals).
Now, as one complete rotation = ${360}^{\circ }$
$\therefore$ Two complete rotation = ${360}^{\circ }+{360}^{\circ }={720}^{\circ }$
