The dollar amount of the meals Sarah served was $1150.

Step-by-step explanation:

Set up an equation expressing Sarah's total earnings:

(total earned) = (base wage) + 0.15 * (price of meals served)

Now the same using what we know:

Firlakuza [10]
We know that

tan 32°=opposite side/adjacent side
[adjacent side]=[opposite side]/tan 32°

in this problem

opposite side-----> will be the altitude of the flock of birds minus your eye level above the ground
(12000-6)-----> 11994 ft

adjacent side------->will be the horizontal distance between you and the birds
32°------> <span>an angle of elevation
</span>
[adjacent side]=[11994]/tan 32°-------> 19194.41 ft

the answer is
<span>The horizontal distance from the birds is 19194.41 ft</span>
