Use the sine law: sinB/b = sinA/a
SinB = b*sinA/a
sinB = 3*sin120° /8
∠ B = 18.94° ≈ 19°

Answer:
t = 640
Step-by-step explanation:
tickets are directly proportional to number of hours.
t =kh
we find K.
240 = 3k
we divide by 3 in both sides.
k = 80
we substitute K to find how many tickets.
t =80 × 8
t = 640
it doesn't matter if you chose any two, e.g., you would get the same answer even if you used 5 and 400, or 9 and 720
F(2) = 24
f(5) = 250
range is {24, 250}
