Answer:
Aplha=105
Step-by-step explanation:
The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
Answer:

Step-by-step explanation:
Exponential equation for population growth:
The exponential equation for a population after t years is given by:

In which P(0) is the initial population and r is the growth rate, as a decimal.
Currently, there are 1,460 wolves in Scataway National Park.
This means that 
Growing at a rate of 6% every year:
This means that
. So
