<h2>Answer:</h2>
720 pounds
<h2>Step-by-step explanation:</h2>Initially, we have that the amount of algae in the pond is . Every four hours the amount of algae doubles. If we called
the time and
the amount of algae, we have that:
Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>

First, in order to find the length of side w, you must first find the angle W.
A triangle must be 180 degrees in total. 93 + 37 makes the triangle only have 130 at the moment.
180 - 130 = 50
So angle W is 50 degrees
Now using this, we can use law of sines.
Now multiply sin 50 on both sides. It can be written like so:
Now plug this in a calculator.
Answer is 39.5
