A lamp pole casts a shadow 49 feet long when the angle of elevation of the sun is 44.8 degrees Find the height of the lamp pole?

A pole casting a shadow 49 feet long with an angle of elevation of the sun of 44.8 degrees is 50 feet tall. (47.98 rounded to two places) Tangent (theta) = opposite / adjac

What is the approximate height of a building when the angle of elevation at the top of a building is 34 degrees and at a point 80 feet closer the angle of elevation is 45 degrees?

It can be shown that: . height = (d tan α tan β)/(tan α - tan β) where: . α is the angle closest to the object . β is the angle further away from the o
