Question

Express the following in to radian measure degree -22°30minute

Answer 1

Step-by-step explanation:

$22deg30min = (22 + \frac{30}{60} )deg$

$= 22.5deg$

$now \: we \: know \: that \\ \\ 1deg = \frac{\pi}{180} rad$

$so \\ 22.5deg = \frac{\pi}{180} \times 22.5 \: rad$

$= 22.5 \times \frac{3.14}{180} (where \: \pi = 3.14)$

$0.3925 \: rad \: \: \: answer$
