A man standing on top of a 100 foot building sites the top of a nearby building at an angle of elevation of 3.14/8. If he knows the nearby building is 160 feet high,what is his horizontal distance from that building.

Answer 1

(3.14/8)/(6.28) * 360 = 22.5o = Angle of elevation.

Tan22.5 = (160-100)/d = 60/d, d = ?.

Answer 2

Note: 3.14/8 Radians = 22.5o.
