In the given figure, a circle with centre O is inscribed inside $\Delta LMN$. A and B are the points of tangency. Find $\angle ANB$.
Show SolutionHide Solution
$\angle AOB = 360^\circ - \text{reflex } (\angle AOB)$
$\angle AOB = 360^\circ - 240^\circ = 120^\circ$ (1 Mark)
$\angle ANB = 360^\circ - (90^\circ + 90^\circ + 120^\circ) = 60^\circ$ (1 Mark)
