Answer: 
Step-by-step explanation:
For this exercise you need to use the Inverse Trigonometric function arcsine, which is defined as the inverse function of the sine.
Then, to find an angle α, this is:

In this case, you can identify that:

Then, substituting values into
and evaluating, you get that the measure of the angle "C" to the nearest degree, is:

Area=length*height
Area=(25)*(8)
Area=200 feet^2
The perimeter would be 16 ft. The area would be 16 ft as well.
