\n" ); document.write( "I agree with tutor Ikleyn. The phrasing \"the distance from you to the dinosaur is 8,500ft\" tells us that the hypotenuse is 8500 ft; but the hypotenuse must be the longest side of the right triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If it was instead phrased as \"the horizontal distance from you to the dinosaur is 8500 ft\", then tutor Theo's drawing would apply.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "However, Theo appears to have misinterpreted what an angle of depression is.
\n" ); document.write( "Angle x of his drawing is NOT the angle of depression. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The angle of depression results when you first look horizontally and then look down at your target.
\n" ); document.write( "Here's an example

\n" ); document.write( "\n" ); document.write( "We must subtract the x value that Theo got from 90 to get the angle of depression.
\n" ); document.write( "90 - x = 90 - 29.54 = 60.46
\n" ); document.write( "Or we could compute it like this
\n" ); document.write( "arctan(15000/8500) = 60.46 approximately
