x=61
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
37+82+x = 180
Combine like terms
119 +x = 180
Subtract 119 from each side
119-119 +x= 180-119
x = 61

Answer:
The population is expected to be 5515 animals in 12 years.
Step-by-step explanation:
This problem can be solved by using a compounded interest formula with a negative interest rate, since the number of animals are decreasing. We have:
final population = initial population * (1 - r)^(t)
Where r is rate of decline and t is the time elapsed. Applying the data from the question we have:
final population = 6000*(1 - 0.007)^(12)
final population = 6000*(0.993)^12 = 5514.9582 animals
The population is expected to be 5515 animals in 12 years.
