___Radian_____ is the basic unit of measurement of an angle.​

Answer 2

Answer: Degree (o) Or Radian(2π)

Concept: Angles

Step-by-step explanation:

Angle subtends at the center of circle , in Radian: 2π rad

Angle subtends at the center of circle , in Degrees: 360°

so,

2π  =  360°

π  =  180°

So,

1 radian  =  180°/π

and,

1°  =  π/180° radian

where,

π = 22/7 or 3.14

Degree measure  =  (180/π) x Radian degree
