From her window, Sandra looks up to the top of a neighboring building at an angle of 36°. Her angle of depression to the bottom of the building is 22°.
The neighboring building is 200 feet away from the building Sandra is in.
How tall is the neighboring building?
+36916 First let's find out how high up Sandra is
Tan 22 = .404
.404 = opp/adj = h1/200
h1 = .404 (200) = 80.8 ft
Now we'll calculate how high the building is ABOVE Sandra
Tan 36 = .7265
.7265 = opp/adj = h2/200
h2 = .7265 (200) = 145.3 ft
Add the tw h's together to get neighboring building height....
