Answer:
0.49 radians or 28.07 degrees
Step-by-step explanation:
Please recall that the definition of the tangent of an angle is "the ratio of the length of the side opposite the angle to the length of the adjacent side, of a right triangle."
Here, opposite side length 8
tan x = ------------------------------------- = ---------
length of adjacent side 15
We use the inverse tangent function to determine the angle x from the given information:
arctan 8/15 = x
Using a calculator, we find that x = 0.49 radians.
The measure of this angle, in degrees, is found by multiplying 0.49 radians by the conversion factor
180 degrees
--------------------
pi radians
which, in this case, works out to 28.07 degrees.

Her estimate is not accurate because if you multiply 30 by 11 you would get 330. Then you multiply that by 52and you would get $10560 a year.
