For this case we must convert the given expression to degrees:
[tex]\frac {3 \pi} {8}[/tex]
By definition we have that [tex]\pi = 180[/tex] degrees, then:
[tex]\frac {3 \pi} {8} * \frac {180} {\pi} = \frac {180 * 3} {8} = \frac {540} {8} = 67.5[/tex]
Thus, we have [tex]\frac {3 \pi} {8}[/tex] is equal to 67.5 degrees.
Answer:
67.5 degrees
