Physics::Measure has this 

https://raku.land/zef:librasteve/Physics::Measure#angles

#Angles use degrees/minutes/seconds or decimal radians
    my $θ1 = ^<45°30′30″>;      #45°30′30″ (using <> to deconfuse quotation marks)
    my $θ2 = ^<2.141 radians>;  #'2.141 radian'
#NB. The unit name 'rad' is reserved for the unit of radioactive Dose

# Trigonometric functions sin, cos and tan (and arc-x) handle Angles
    my $sine = sin( $θ1 );      #0.7133523847299412
    my $arcsin = asin( $sine, units => '°' ); #45°30′30″
#NB. Provide the units => '°' tag to tell asin you want degrees back

it uses Physics::Unit which has this…

Angle:
  - {names: [°, degree, deg, º],         defn: 'pi radians / 180'}
  - {names: [ᵍ, gon, grad],              defn: 'pi radians / 200'}

and

- Angle:       [radian, rad]   (ie the default is rad)

There is also Physics::Navigation… that adds on lat/long and bearing (ie points of compass and modulo math)
