Question
Find the angle measure $x$ in the figure.
✓
Answer
Let each angle of the pentagon be $'x'$
$x + x + x + x + x = (5 - 2) \times 180^\circ $ [ By angle sum property of a pentagon]
$\therefore $ $5x = 540^\circ $
$\therefore $ $x = \frac{{540^\circ }}{5}$
$\therefore $ $x = 108^\circ $
$x + x + x + x + x = (5 - 2) \times 180^\circ $ [ By angle sum property of a pentagon]
$\therefore $ $5x = 540^\circ $
$\therefore $ $x = \frac{{540^\circ }}{5}$
$\therefore $ $x = 108^\circ $
