Step-by-step explanation:
Let h m be the height of the tower and m be the depth of tank; now in triangle ABC; tan 30 =BC/AB 1/√3 =h/40 h=40/√3 ............................1 IN tringle ABD tan 45 =DC +BC/AB 1=x+h/40 x+h=40 using 1 x+40/√3=40 x=40 bracket ma 1-1/√3 m then HEIGHT=40/√3 m DEPTH= 40/ bracket ma 1-1/√3
