Answer
A
StartFraction sine 105 degree over 15 EndFraction = StartFraction sine 30 degree over q EndFraction
B
StartFraction sine 105 degree over q EndFraction = StartFraction sine 30 degree over 15 EndFraction
C
StartFraction 15 over sine 105 degree EndFraction = StartFraction q over sine 45 degree EndFraction
D
StartFraction q over sine 105 degree EndFraction = StartFraction 15 over sine 45 degree EndFraction
