Answer:
An arc is a segment of a circle around the circumference. ...
To be able to calculate an arc measure, you need to understand angle measurements in both degrees and radians. ...
360° = 2π radians.
180° = π radians.
arc measure = sr.
arc measure = 34.

Answer:
The major arc subtends angle 2x and the minor arc subtends angle x
Since the length of arcs depend upon the angle subtended at the centre
2x+x=36o(complete angle)
3x=120o×3
x=120o
Hence major arc subtends 240o and minor arc subtends 120o
