Answer:
∅ ≈ 56.31°
Step-by-step explanation:
The bird is spotted flying 6000 ft from a tower . The distance of the tower from the bird is 6000 ft. The height of the tower is 9000 ft because the observer spot the distance from the top of the tower at a distance of 9000 ft.
The illustration forms a right angle triangle. The adjacent side of the triangle is 6000 ft and the height or opposite side of the triangle is 9000 ft. Using tangential ratio the angle of depression from the bird to the observer can be found as follows.
Let
∅ = angle of depression
tan ∅ = opposite/adjacent
tan ∅ = 9000/6000
tan ∅ = 1.5
∅ = tan⁻¹ 1.5
∅ = 56.309932474
∅ ≈ 56.31°
The answer is f(x)=x because the ratio of rise over run is 1/1

area of parallelogram: base × height = 17.6 cm sq
⇒ 4 × h = 17.6
⇒ h = 17.6/4
⇒ h = 4.4 cm
Step-by-step explanation:
20% of 220 is 44 people so if you divide 220 by 2 you have 110 of each then add 44 to one and subtract 44 from the other the answer to a is 154 and the answer to b is 66
