Explanation:
We can find the coterminal angle by simply adding or subtracting 360° to each angle. In this problem, we need to find the smallest positive coterminal angle with 915 degrees.
It can be calculated by adding or subtracting 360° to the given angle. For positive coterminal angle subtract 360° from 915°
915-360 = 555
555-360 = 195
The positive coterminal angles: 195°, 555°, 915°, 1275°, 1635°...
The negative coterminal angles: -165°, -525°, -885°, -1245°...
Hence, the angle 195° is the smallest positive coterminal angle with 915 degrees
