Answer:
x = 12.52°
Step-by-step explanation:
The illustration forms a right angle triangle . The right angle triangle formed has a height of 200 ft and a base of 900 ft.
The opposite side of the triangle is 200 ft while the adjacent side of the triangle is 900 ft.
Using tangential ratio we can find the angle of depression. Therefore,
Let
x = angle of depression
tan x = opposite/adjacent
opposite = 200 ft
adjacent = 900 ft
tan x = 200/900
tan x = 2/9
x = tan⁻¹ 2/9
x = tan⁻¹ 0.222
x = 12.5166739144
x = 12.52°

Answer: Michael has 87 comic books while David has 41 comic books.
Step-by-step explanation:
Let x represent the number comic books that Michael has.
Let y represent the number of comic books that David has.
Michael has 5 more comic books than double David's collection. The expression would be
x = 2y + 5
If together they have a total of 128 comics, it means that
x + y = 128- - - - - - - - - -1
Substituting x = 2y + 5 into equation 1, it becomes
2y + 5 + y = 128
3y + 5 = 128
3y = 128 - 5
3y = 123
y = 123/3
y = 41
Substituting y = 41 into x = 2y + 5, it becomes
x = 2 × 41 + 5
x = 87
