A surveyor standing 2,227 ft from the base of the World Trade Center in New York City measured a 31 degrees angle to the topmost point. To the nearest feet, how tall is the World Trade Center?

Answer 1

Tangent = opp/adj

tan 31 = x/2227

find tan 30 degrees and multiply that answer by 2227.

Answer 2

My answer: 1,368 feet

Answer 3

I wrote tan of 30 instead of tan 31

If you use tan 31, you should get 1338.
