Question

convert 40°20` into radian measure

Answer 1

See the Answer Below Mate:-

=>40°20'

Solving, The equation :-

=>40°+20'

=>40°+(20°)/(60)                                           .....................................[∵ 1° = 60']

=>40°+1/3

=>(120°+1)/3

=>121°/3

We, Know that :

                   $Radian$ $Measure$ = $\frac{π}{180}$ × $Degreee$ $Measure$

=>$\frac{π}{180}$ × $\frac{121}{3}$

=>$\frac{121}{540}$π Radians
