Question

20°50' convert into radian

Answer 1

Answer:

20° 50'

1°=60'

50'/60 = 0.8

= 20.8

radian = π/180×degree

= π/180×20.8

= 20.8π/180

Answer 2

Answer:

=0.1157π rad

=0.363298 rad

Explanation:

1°=60'

1'=(1÷60)°

50'=50/60°=0.83°

∴20.83°

radian=degree*π/180

         =20.83*π/180

          =0.1157π rad
