Which of these is equivalent to
3π/5 rad ?
A) 108°
B) 150°
C) 216° **my answer
D) 300°
It's A)108
Just took test
2π rad = 360º ... π rad = 180º
3 * 180 / 5 = ?
To determine which of these options is equivalent to 3π/5 rad, you need to convert the given angle measure from radians to degrees. The conversion between radians and degrees is as follows:
180° = π radians
To convert radians to degrees, you can use the formula:
degrees = radians × (180° / π)
Let's apply this formula to determine the equivalent angle measure for 3π/5 rad:
degrees = (3π/5) × (180° / π)
By simplifying this expression, the π units cancel out:
degrees = 3 × (180° / 5)
degrees = 3 × 36°
degrees = 108°
Therefore, option A) 108° is the correct answer.
