Answer:
-10.21 radians
Step-by-step explanation:
2π radians =360°
1radian=360°/2π
=57.2958°
Therefore to get the number of radians in -585°,
letting the number of radians to be x, we can calculate
if 1radian=57.2958°
x radians=-585°
the following expression is thus obtained
x=(-585°×1)/57.2957°
=-10.21radians
