Answer:
29π/108 radians ≈ 0.843576 radians
Step-by-step explanation:
There are 60 minutes (60') in a degree, so your angle in degrees is ...
48°20' = (48 20/60)° = (48 1/3)° = (145/3)°
There are π/180 radians in 1 degree, so the number of radians is ...
(145/3)(π/180) = 29π/108 radians ≈ 0.843576 radians
