find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle -15pi/17
natta225 [31]
ANSWER
=\frac{19}{17} \pi

EXPLANATION

To find a positive angle that is coterminal with
-  \frac{15}{17}  \pi

We add multiples of 2π until we get a positive angle that is less than one revolution,


We add to obtain,


-  \frac{15}{17}  \pi + 2\pi


This simplifies to,

=  \frac{19}{17} \pi

This is the first positive angle that is coterminal with
-  \frac{15}{17}  \pi


and is less than one revolution.
