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°
Answer:
T will equal 4
Step-by-step explanation:
T-4=T-4
T+4=T+4
Answer:
(3,1.5)
Step-by-step explanation:
Finding the midpoint of 2 endpoints (or just two points) can be done with the equation (x1+x2)/2 and (y1+y2)/2. When I say x1 I mean the x-value of the first coordinate which would be -2 and when I say y1 i mean the y-value of the first coordinate which is 6. So plugging in the coordinates would give you (-2+8),(6+-3). Now you add your terms together and get the numbers (6) and (3). After that you must divide those number by two so (6)/2 and (3)/2 which would equal (3,1.5).
