Answer:
90 beats per minute
Step-by-step explanation:
By looking at the graph, we see that exactly at second 6, the 9th beat occurs. We can take that to beats/min by multiplying that relation by 10 (since there are ten 6sec in one minute).
9beats every 6sec * 10 = 90beats/min
Angle of fire in degrees = 90 + 30 =120 degrees
Angle of fire radians =180 degrees = π
120* π/180=120π /180 OR 4π/6 OR 2π/3
