Answer:
I'm sorry I don't know
Step-by-step explanation:
hopefully someone solves this!
To solve this, I would square root all of the possible answers and see which ones the arrow falls between. After that I would choose the answer closest to it.
Hope this helps!
Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let

the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.




We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is

.
I think it would be B ?? Because it’s the shortest one ♀️
Answer: see below
<u>Step-by-step explanation:</u>
If the figures are similar, then their corresponding sides are proportional.
ABCD ~ WXYZ
