Answer 1

Just try to form a triangle,so that we can apply "Trigonometric ratios"

In the final triangle of our figure, 
Perpendicular = 32.5 - 6 = 26.5 Feet
Base = 110 Feet [ Given ]

Now, We know, Tan Ф = P / B
Tan Ф = 26.5 / 110
Tan Ф = 0.240

We know, Tan 13.5 = 0.240
So, Ф = 13.5

In short, Your Angle of Elevation would be 13.5 degrees

Hope this helps!
