If an arc has measure 7π/4 radians then it will be having 315 degrees and 60° in radian is π/3.
Given that arc has measure of 7π/4.
We are required to convert the measure from radian to degree measure.
Converting means chaning of units from one to another.
To convert 7π/4 into degrees we have to just put π=180 then we will get the value in degrees.
7π/4=7*180/4
=7*45
=315 degrees
Now we have to convert 60 degrees into radians.
60 degrees=60*π/180
=π/3
Hence if an arc has measure 7π/4 radians then it will be having 315 degrees and 60° in radian is π/3.
