9. A person stands at the window of a building so that his eyes are 12.6 m above the level ground. Anobject is on the ground 58.5 m away from the building on a line directly beneath the person. Compute
the angle of depression of the person's line of sight to the object on the ground.
Answers
The angle of depression of the person's line of sight to the object on the ground is 12.15°.
The information forms a right angle triangle. The person eyes above the ground is the opposite side of the triangle. The object distance from the building in line of the sight is the adjacent side of the right angle triangle.
Therefore,
using trigonometric ratio,
tan Ф = opposite /adjacent
tan Ф = 12.6 / 58.5
tan Ф = 0.21538461538
Ф = tan⁻¹ 0.21538461538
Ф = 12.1549416972
Ф = 12.15°
angle of depression ≈ 12.15°

X - 3X = 2(4+X)

Subtraction Property:

Division Property:
x = 8/-4
X = -2
Hi,
Let's solve the equation step-by-step.
x−3x=2(4+x)
Step 1: Simplify both sides of the equation.
x−3x=2(4+x)
x+−3x=(2)(4)+(2)(x)(Distribute)
x+−3x=8+2x
(x+−3x)=2x+8(Combine Like Terms)
−2x=2x+8
−2x=2x+8
Step 2: Subtract 2x from both sides.
−2x−2x=2x+8−2x
−4x=8
Step 3: Divide both sides by -4.
−4x/−4 = 8/−4
x=−2
Answer:
x=−2

two - point six
is the answer
The answer you are looking for is "Two and six tenths".
The reason this is, is because 2 is left of the decimal, which makes it "two". Since 6 is to right of the decimal, you have to look at how far it is from the decimal. It being directly after the decimal, it is in the tenths place, making it six tenths. Thus meaning the answer is two and six tenths.
I hope this helps!
