Answer:
<em> 3 years old </em>
Step-by-step explanation:
( 21 + 24 + 18 + 15 + 15 + x ) / 6 = 16
93 + x = 96
x = 3

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
Considering the least common factor of 15 and 18, it is found that they will depart from the central station at the same time at 11 AM.
<h3>How to find the time it takes for periodic events to repeat at the same time?</h3>
To find the time that passes between the events happening at the same time, we need to find the least common multiple of the periods.
In this problem, the periods are of 15 and 18, hence their lcm is found as follows:
15 - 18|2
15 - 9|3
5 - 3|3
5 - 1|5
1 - 1
Hence:
lcm(15,18) = 2 x 3 x 3 x 5 = 90 minutes.
They will depart from the central station at the same time in 90 minutes from 9:30 AM, hence at 11 AM.

Answer: Its C
Step-by-step explanation:
Well, this irrational, or never-ending, ratio starting with 1.618 has been given many names over the years including the “golden ratio” and the “divine proportion”.
