Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
I did the math and I think that it's 3.7
