First calculate the missing angle 
. By knowing all angles in triangle have a sum of 180°.
Now we required to use angle functions in a right triangle. The cosine of
is equal to the relation of side 
and hypotenuse 
.
Now we solve this for hypotenuse.
Now put in the numbers.
So we know the length of hypotenuse and length of side therefore side 
can be calculated using Pythagorean theorem: 
.
Solve for side.
So there you go. If you have any questions feel free to ask.

we can sue formula
where
P(t) is population after t years
P0 is initial population
k is growth rate
t is time in years since 1985
Let's assume
h(t)=P(t) is million
h_0=P_0 in million
we can replace it
and we get
