MCQ
Each interior angle of a regular decagon is
  • A
    $124^{\circ}$
  • B
    $120^{\circ}$
  • $144^{\circ}$
  • D
    $140^{\circ}$

Answer

Correct option: C.
$144^{\circ}$
(C) $144^{\circ}$
[Hint: Each exterior angle $=\frac{360^{\circ}}{10}=36^{\circ}$ So, each interior angle $\left.=\left(180^{\circ}-36^{\circ}\right)=144^{\circ}\right]$
