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?

First let's find out how high up Sandra is

Tan 22 = .404

.404 = opp/adj = h_{1}/200

h_{1} = .404 (200) = 80.8 ft

Now we'll calculate how high the building is ABOVE Sandra

Tan 36 = .7265

.7265 = opp/adj = h_{2}/200

h_{2 }= .7265 (200) = 145.3 ft

Add the tw h's together to get neighboring building height....
