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:
k - 8.1 > 24
Step-by-step explanation:
difference = subtraction
greater than 24 = > this sign
Answer:
yes, the subtracting of two rational numbers is like subtracting two fractions, and the result will always be a fraction which is a rational number. (All rational numbers is a number that can be represented as a fraction)

Answer:
8.1 inches
Step-by-step explanation:
Proportion of angle to the whole circle:
(13π/18)/2π=13/36
13/36=18.4/2rπ
13/36=9.2/rπ
13rπ=331.2
rπ=25.47
r=8.1
Step-by-step explanation:
9.9²
(10-0.1)²
= 10² -2 (10) (0.1) + 0.1²
= 100 -2 + 0.01
= 98.01
