Answer:

Step-by-step explanation:
You need 2 things in order to solve this equation: a trig identity sheet and a unit circle.
You will find when you look on your trig identity sheet that

so we will make that replacement, getting everything in terms of sin:

Now we will get everything on one side of the equals sign, set it equal to 0, and solve it:

We can factor out the sin(theta), since it's common in both terms:

Because of the Zero Product Property, either
or

Look at the unit circle and find which values of theta have a sin ratio of 0 in the interval from 0 to 2pi. They are:

The next equation needs to first be solved for sin(theta):
so
and

Go back to your unit circle and find the values of theta where the sin is -1/2 in the interval. They are:

-17/2
Step-by-step explanation:
30-8(8)+4y
30=64+4y
30-64=4y
-34=4y
y= -34/4
y= -17/2

Total area = 2,250 ft + 706.50 ft = 2,956.50 ft. pretty sure that’s the answer.
No that is an inverse variation, a direct variation must have a y that is directly proportional to x while the picture shows a y that is inversely proportional to x <span />
