Construct an angle of $7 \frac{1}{2}^{\circ}$ and write the steps of construction.

(N/A) To construct an angle of $7 \frac{1}{2}^{\circ}$ (which is $7.5^{\circ}$),follow these steps:
$1$. Draw a ray $OA$.
$2$. Construct a $60^{\circ}$ angle using a compass and ruler.
$3$. Bisect the $60^{\circ}$ angle to get $30^{\circ}$.
$4$. Bisect the $30^{\circ}$ angle to get $15^{\circ}$.
$5$. Bisect the $15^{\circ}$ angle to get $7 \frac{1}{2}^{\circ}$.
Since $7 \frac{1}{2}^{\circ} = \frac{15^{\circ}}{2}$,this is the required angle.
