The tangent of an angle is the ratio of the opposite side to the adjacent side.
... tan(45°) = (height above eye level)/(20 m)
... height above eye level = (20 m)·tan(45°) = (20 m)·1 = 20 m
_____
Eye level is 1.7 m above ground, so the height of the flagpole above ground is
... height of pole = height above eye level + height of eye level
... height of pole = 20 m + 1.7 m = 21.7 m
In 1 US Quarts, there are 0.946353 Liters.
In 1 Liter, it is equal to 1.05669 Quarts
If there are 12 L, multiply it 1.05669 Quarts.
So the answer is 12.6803. Letter C.
What do u want it to be equivalent to?
