Question

ayudaaaaaaaaaa, porfiiii​

Answer 1

Explicación paso a paso:

Recordemos que 1π rad = 180°

a)

1π rad --------------->180°

X <-------------------132°

X = π rad × 132°/180°

X = 11/15 πrad

b)

72° 59'48"

59/60 = 0.983

48/3600 = 0.0133

72 + 0.983 + 0.013 = 72.996°

c)

1

1π rad -------------->180°

9π rad -------------->X

X = 1620°
