Question 1138367
<font face="times" color="black" size="3">
To convert from radians to degrees, you multiply by {{{180/pi}}}


{{{((-7pi)/6)*(180/pi)}}}


{{{((-7cross(pi))/6)*(180/(cross(pi)))}}} note how a pair of {{{pi}}} terms cancel


{{{(-7/6)*180}}} 


{{{-7*(180/6)}}} 


{{{-7*(30)}}} The 180 divided by 6 leads to 30


{{{-210}}} 


The angle {{{(-7pi)/6}}} radians is equivalent to {{{-210}}} degrees. 


You can add 360 to -210 to get to -210+360 = 150
Meaning that -210 and 150 are coterminal angles, ie, they point in the same exact direction.
