The population of the group in 2019 is 2,134,000 people
Let P represent the population in thousands of people in the year t after 2011
Given the equation:

a) The population of the group in 2019, that is t = 8(2019 - 2011):

b) The population of the group in 2029, that is t = 18(2029 - 2011):

The population of the group in 2019 is 2,134,000 people

Answer:
75
Step-by-step explanation:
If the triangles are similar, it means the ratio between the two give sides is the same. As seen from the smaller triangle the ratio of the two top sides would be 16:50 or 8:25.
Since the first side of the bigger triangle (24) is three times 8 (it's ratio side), then the other side must be 3x25 = 75, which maintains the ratio 8:25 between the two sides (24:75).
Hope this helped!
