Answer 2

Answer:

we know that 180⁰= π radian.

1°=60'

1'=60"

$Hence \: 1'=( \frac{1}{60})^{°}$

$40°+20×( \frac{1}{60})°$

$40⁰+20×( \frac{1}{3}) \: digree$

$\frac{121}{3} \times \frac{\pi}{180} \: radian$

$= \frac{121\pi}{540} \: radian$

$Therefore \: \: 40°20'= \frac{121\pi}{540} \: radian$
