Question 90236
Prefered:
 a. draw a building with an antenna on the top
 b. draw a line near the base of the building to the top of the building
 c. draw a line from the same spot to the top of the antenna
 d. label
~ 1000 + x is the total height where x is the height of the antenna
~ b is the distance the location of the spot near the base is from the building
tan(62.6*) = 1,000/b or b = 1,000/tan(62.6*)
tan(65.8*) = (1,000 + x)/b or (1,000 + x)/tan(65.8*) = b
b = b
1,000/tan(62.6*) = (1,000 + x)/tan(65.8*)
1,000*tan(65.8*)/tan(62.6*) = 1,000 + x
1,000*tan(65.8*)/tan(62.6*) - 1,000 = x
