From the top of a tower, the angle of depression to the bottom of a pillar on the same surface of height 20m is 60° If the a angle of depsession from the top of the . pillar to the bottom of the lower is 22. find the height of the tower. ( Ton 220 - 0,4)

Let AB=height of the building=100m

DE=AC=AB+BC=h= height of the tower

∠ADC=60

∘∠BDC=60 ∘

Now

tan30 ∘ = CDCB

= dx

31 = dx

(1)tan60 ∘ = CDCA

= dx+100

3 = dx+100

(2)From (1)d= 3

x (3)Substituting (3) in (2)

3 = 3 x(x+100)

3x=x+100

2x=100

x=50

Height of the tower=DE=h=AB+CB=100m+x=100m+50m=150m

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
