\n" ); document.write( "
The distance from the plane to the building is actually the same as the distance from the building to the point on the GROUND, directly below the plane. Therefore, with a right-triangle

document.write( "being formed, with the side opposite the 28o∡ being 1,200 m, and the unknown adjacent side (D) being sought, we get the following trigonometric function: 
\n" );
document.write( "Solve this for D, the distance from the plane to the building!
\n" );
document.write( "Note that the 28o∡ of depression is from the plane to the BASE/BOTTOM of the building, and not the TOP. \n" );
