1.	Calculate the angle ola (b) 1 minute of arc or arcmin)nd (c) 1° (second of arc or arc second) inUse 360°=2π rad. 1°-60, and t= 60
Answer» We know 3600= 2π rad =>1°= (π/180) rad = 0.01745 rad 1/= (1/60)°= π/(60 × 180) = 0.00029 rad 1//= (1/3600)°= π/(3600 × 180) = 0.0000048 rad

Answer»

We know 3600= 2π rad

=>1°= (π/180) rad = 0.01745 rad

1/= (1/60)°= π/(60 × 180) = 0.00029 rad

1//= (1/3600)°= π/(3600 × 180) = 0.0000048 rad
