Answer:
45 feet deep
Step-by-step explanation:
First the formula for Parabola is: 4py=x2, we will make it as if it were in the center of the graph.
Now P is the distance from the vertex to the focus or to the directrix which is equal to 20.
4(20)y=x2
80y=x2
Now we just have to use one knwon value of X in the maximum point of the dish, is the diameter of the dish is 120 feet that is the maximum x, and we know that 120 feet is te distance between the widest -x and x, so those would be: -60 and 60.
We will use 60 as our value:
So we know that the depth of the parabolic dish is 45 feet.

ANSWER
EXPLANATION
We use the sine rule to obtain,
We multiply both sides by 4 to obtain,
We take the inverse sine of both sides to get,
to the nearest tenth.
The correct answer is -18
