X={6,-10} that is the answer
Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.
Let x = angle of elevation.
By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)
Answer: 35°
0.123456789 not even joking thats the answer I did it on a calculator ♀️
The first option and the third option are correct.
(Although, it's probably way too late now...)
