Question

I am walking towards a building I'm 75 feet away. I look up to the top of the building and I know it's 35 feet tall at what angle of elevation am I looking up at

Answer 1

apply trigonometric functions:

Tan a = opposite side / adjacent side

Where:

a = angle = x

opposite side = 35

Adjacent side = 75

REplacing:

Tan x = 35 /75

Solve for x

x = arctan (35/75)

x = 25°
