Determine the angle of the sun above the horizon based on the time of day.
Assumptions: the sun rises in the East at 6h00, corresponding to an angle of 0° degrees; reaches its zenith at 12h00, with an angle of 90° degrees; and sets at 18h00, with an angle of 180° degrees.
Input: The time of day represented as a list [hh, mm], where
and
.
Output: The angle of the sun above the horizon, in degrees, rounded to 2 decimal places. If the input time falls within the night hours (before 6h00 or after 18h00), your function should return 'Night'.
Example:
- sun_angle([7,0]) should return 15.00
- sun_angle([12,15]) should return 93.75
