Answer:
about 71.6°
Step-by-step explanation:
The relevant trig function is ...
Tan = Opposite/Adjacent
Here, the "opposite" side of the right triangle is the height of the tower. The "adjacent" side is the distance to the tower. Then if the angle is x, we have ...
tan(x) = 900/300 = 3
x = arctan(3) ≈ 71.6°
Megan's angle of elevation is about 71.6°.

Answer:
Step-by-step explanation:
We look for where 
. The way you find the answer is first, find the point 
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that 
intersects our line at 
, so .
