a)
Subtract 360 from 520
520 - 360 = 160
Coterminal 520° is 160°
b)
Multiply 360 times 2
360 x 2 = 720
Subtract 720 from 735
735 - 720 = 15
coterminal 735° is 15°
c)
Subtract - 170 from 360
360 - 170 = 190
Coterminal - 170° is 190°

co terminal would mean that at wat other angle would that be the same as (use +- 360 deg) for degrees.
since its asking for the smallest pos. measure then, ur looking for an angle between 0 aand 360 degrees.
a. 520 deg -- its coterminal would be 520-360= 160
b. 735 deg -- 735 - 720 = 15
c. -170 deg -- -170+360 = 190
