Amplitude:19.1

Period:2π/30=π/15

Phase Shift:
30t+240=0
30t=-240
t=-8
-8

Vertical Shift:
7.5

amp = 19.1

period = pi/15 ; pi=3.14...

phase shift= 8 units left

verticl shift = 7.5 units up

Just take the numbers and the words as they occur in order and match them to each other. That's your answer.
