Given Height of pole = DE = 6 m Length of shadow = EF = 2βπm We need to find Angle of elevation of the sun i.e π In β π·πΈπΉ tan π = (ππππ πππππ ππ‘π π‘π πππππ" " πΉ)/β(ππππ ππππππππ‘ π‘π πππππ" " πΉ@ ) tan π½ = (" " π«π¬)/π¬π tan π = (" " 6)/(2β3) tan π = (" " 3)/β3 tan π =β3 β΄ π½ = 60 Β° So, the correct answer is (a)
