Two points, A and B, are 526 apart on a level stretch of road leading to a hill. The angle of elevation of the hilltop from A is 26°30', and the angle of elevation from B is 36°40'. How high is the hill

if cosec alpha +cot alpha =2√3than prove that cos alpha =2\√5

cos3tita+3costitasin2tita=x‚sin3tita+3sintitacos2tita=y

if cosec alpha +cot alpha =2√3 than prove that cos alpha =2\√5
