.
draw a diagram and then apply trig...
.
Let d = distance
then
tan(37) = d/105
105 * tan(37) = d
79.12 feet = d

----------------------
Draw the picture.
You have a right angle with height = 105 ft. and angle
opposite = 37 degrees.
---
tan(37) = height/dist
dist = height/tan(37)
dist = 105/0.7536
dist = 139.34 ft.
