For this case what you should do is use the following trigonometric relationship:
sine (theta) = C.O / h
Where,
theta: angle
C.O: opposite leg
h: hypotenuse
Substituting values we have:
sine (80) = 9 / x
Answer:
sine (80) = 9 / x

Answer:
7.0 m/s
Step-by-step explanation:
We can solve this using the 2 kinematic equations and you can use either:
So let's use the first one.
Vi = initial velocity
Vf = final velocity
a = acceleration due to gravity (constant 9.8m/s²)
t = time
The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.
We are given then the following:
d = 2.5m
t = 0.71s
Vi = 0 m/s
a = 9.8m/s²
So we plug in the values we know and solve:
