Question:
Express each of the following angles in radians
$7^{\circ} 30 .^{\prime}$
Solution:
Formula: Angle in radians $=$ Angle in degrees $\times \frac{\pi}{180}$
The angle in radians $=\frac{\text { angle in minutes }}{60}$
Therefore, the total angle $=7+\frac{30}{60}=7.5$
Therefore, Angle in radians $=7.5 \times \frac{\pi}{180}=\frac{\pi}{24}$
