4/5 divided by 1/5 = 1/4 or 0.25
Answer:
18
Step-by-step explanation:
There are 6 dots. The number of ways we can select 3 from 6 is:
₆C₃ = 6! / (3! (6−3)!)
₆C₃ = 6! / (3! 3!)
₆C₃ = 6×5×4 / (3×2×1)
₆C₃ = 20
However, 2 of these combinations are lines, not triangles.
So there are 18 possible distinct triangles.
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
