Coterminal angles are angles that, starting on the same place of the unit circle, end up in the exact same spot.
Because the circle has 360°, a coterminal angle can always be found by adding or substracting 360° from the given angle. These are th same as making a complete round on the circle, that is why it will end up in the same spot.
We want a coterminal angle of 395° less than 360°. Since 395° is greater than 360°, we can substract 360° to find a coterminal angle less than 360°.
Substracting once will already got where we want:
Thus, a positive angle less than 360° that is coterminal with 395° is 35°.
