=
, substitute values
=
( cross- multiply )
16 sinA = 8 sin35° ( divide both sides by 16 )
sin A =
, thus
∠ A =
(
) ≈ 16.67° ( to 2 dec. places )

Answer:
Best estimate for the bee population is 1280.
Step-by-step explanation:
Randy marked total number of bees = 160
Then he collected 240 bees and observed that number of bees marked
= 30
We have to find the total population of the bee or best estimate for the bee population.
Now we use the ratio of marked bees in the sample vs marked bees in the total population


x = 
Therefore, the best estimate for the bee population is 1280.
