Answer:
So I can't actually do this at the moment but I'll try to explain what to do
first find the area of the rectangle (12x16)
then, the confusing part, pretend the semicircle is a full circle and find the area and divide by 2
add the two up and put and that should be it
The positions of the sun, earth and shooting star form a right angled triangle, where distance between earth and sun is 'y', and the angle 'x°' is given
Now, in a right angled triangle using trigonometry, we can determine a side of the triangle is one of the sides and one of the angles is known
Here, if we use cos x = we can determine the distance between the shooting star and the sun. This can be done because we know that the base is 'y', the angle is x° and the hypotenuse represents the distance between the sun and the shooting star
Note: cos values for each x are definite.
The function is undefinded if the denominator, x-5, equals 0.

The domain is

In interval notation, this is (-infinity, 5) u (5, infinity).
