Convert rev/min to radians per min:
(7 rev/14 min) * (2pi rad/1 rev) = pi radian/min
Convert rad/min to rad/sec. This is the angular velocity:
(pi rad/min)*(1min/60 sec) = pi/60 rad/sec
Linear velocity = angular velocity * radius
(pi/60 rad/sec) * 30ft = 0.5pi ft/sec
Convert ft/sec to in/sec:
(0.5pi ft/sec) * 12 in/1 ft = 6pi in/sec

Answer:
x = 50.5°
Step-by-step explanation:
Use SOH CAH TOA... Since the adjacent and hypotenuse are given, you must use cosine.
cos(x) = 14/22
cos^-1 (14/22) = 50.5°
