Answer:
cos theta=4/5
b/h=4/5
b=4 and h=5
p=?
H^2=P^2+B^2
5^2=P^2+4^2
25-16=P^2
9=P^2
=P
3=P
Now,
sin2theta
=p/h2
=3/5*2
=9/5

<u><em>The correct question is</em></u>
Find the cosine of ∠A
The picture in the attached figure
we know that
In the right triangle ABC
The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse of the right triangle
so
----> by CAH
substitute the given values

Step-by-step explanation:
Area of central park = 2.5 × 0.5 = 1.25 square mile
1 acre = 1/640 square mile
1.25 square mile = 1.25 ÷ 1/640 = 800 acre
Number of people in the park = 800 ÷ 15 = 53.3 ≈ 53 people
