Isaac is looking through binoculars on a whale watching trip when he notices a sea otter in the distance. If he is 20 feet above sea level in the boat, and the angle of depression is 30 degrees, how far away from the boat is the otter (to the nearest foot)?

Best ResponseYou've already chosen the best response.0\[\tan \theta =\frac{ 20 }{ x }\] so here we want x, therefore multiply both sides by x, to get \[xtan \theta =\frac{ 20 }{ x }.x\] \[x \tan \theta =20\] divide both sides by tan o gives \[\frac{ x \tan \theta }{ \tan \theta }=\frac{ 20 }{ \tan \theta } \] w/c gives \[x=\frac{ 20 }{ \tan \theta }....\] x=?
