1)Transformar 150˚ a radianes
150˚x π/180˚ = 2.62 rad
150˚x π/180˚ = 5/6 π
2)Transformar 120˚ a radianes
120˚xπ/180˚ = 2.09 rad
120˚xπ/180˚ = 2/3 π
3)Transformar 270˚ a radianes
270˚xπ/180˚= 4.71 rad
270˚xπ/180˚= 3/2 π
4)Transformar 1.7 radianes a grados
1.7x180˚/π= 97.40˚
5)Transformar 2.1 radianes a grados
2.1x180˚/π= 120.32˚
6)Transformar 7/4 radianes a grados
7/4x180˚/π= 100.26˚
