What is the missing number?
− 2 = 4
OK, the answer is 6, right? Because 6 − 2 = 4. Easy stuff.
Well, in Algebra we don't use blank boxes, we use a letter (usually an x or y, but any letter is fine). So we write:
x − 2 = 4
It is really that simple. The letter (in this case an x) just means "we don't know this yet", and is often called the unknown or the variable.
And when we solve it we write:
x = 6

The perimeter of a rectangular school yard is 264 meters. The school yard is 89 meters long. How wide is it?
Answer:
43 meters
Step-by-step explanation:
Perimeter is 2l+2w
l equals length
w equals width
264 = 2*89 + 2w
264 = 178 + 2w
264 - 178 = 2w
2w = 86
w = 43

Answer:
39.4 feet
Step-by-step explanation:
The tangent trig relation can be used to relate the height of the tree to the distance from the observation point. We can start with the tangent relation, then apply it to both observation points.
__
Let h represent the height of the tree. Then for some distance d to the tree, we have ...
Tan = Opposite/Adjacent
tan(30°) = h/d
tan(20°) = h/(d+40)
__
Solving the first equation for d and substituting into the second equation gives ...
d = h/tan(30°)
tan(20°) = h/(h/tan(30°) +40) . . . . . substitute for d
h/tan(30°) +40 = h/tan(20°) . . . . . . multiply by (h/tan(30°)+40)/tan(20°)
h(1/tan(20°) -1/tan(30°) = 40 . . . . . subtract h/tan(30°) and factor
h = 40tan(20°)tan(30°)/(tan(30°) -tan(20°)
h ≈ 39.392 . . . feet
The height of the tree is about 39.4 feet.
_____
As you can see from the attachment, a graphing calculator can solve these equations easily.
Answer:
39.4 ft (nearest tenth)
Step-by-step explanation:
Create two equations using trig ratios and the information given (refer to the attached diagram). Equate the equations and solve.
First equation
Let x = distance along the path with 30° angle of elevation
Let h = height of the tree
Using the tangent trig ratio:
[tex]\mathsf{\tan(\theta)=\dfrac{opposite \ side}{adjacent \ side}}[/tex]
Given:
angle = 30° side opposite the angle = hside adjacent the angle = x[tex]\implies \mathsf{\tan(30)=\dfrac{h}{x}}[/tex]
Rearrange to make x the subject:
[tex]\implies \mathsf{x=\dfrac{h}{\tan(30)}}[/tex]
[tex]\implies \mathsf{x=\sqrt{3} \ h}[/tex]
Second equation
Distance along the path with 20° angle of elevation = x + 40
Let h = height of the tree
Using the tangent trig ratio:
[tex]\mathsf{\tan(\theta)=\dfrac{opposite \ side}{adjacent \ side}}[/tex]
Given:
angle = 20° side opposite the angle = hside adjacent the angle = x + 40[tex]\implies \mathsf{\tan(20)=\dfrac{h}{x+40}}[/tex]
Rearrange to make x the subject:
[tex]\implies \mathsf{x=\dfrac{h}{\tan(20)}-40}[/tex]
Now equate the 2 equations and solve for h:
[tex]\implies \mathsf{\sqrt{3} \ h=\dfrac{h}{\tan(20)}-40}}[/tex]
[tex]\implies \mathsf{\dfrac{h}{\tan(20)}-\sqrt{3} \ h=40}}[/tex]
[tex]\implies \mathsf{\dfrac{h-\sqrt{3} \ h\tan(20)}{\tan(20)}=40}}[/tex]
[tex]\implies \mathsf{h-\sqrt{3} \ h\tan(20)=40{\tan(20)}}[/tex]
[tex]\implies \mathsf{h(1-\sqrt{3} \tan(20))=40{\tan(20)}}[/tex]
[tex]\implies \mathsf{h=\dfrac{40{\tan(20)}}{1-\sqrt{3} \tan(20)}}[/tex]
[tex]\implies \mathsf{h=39.39231012...}[/tex]
Therefore, the height of the tree is 39.4 ft (nearest tenth)

An observatory is 150 feet high. When a person is standing in the observatory looking at an island, the angle of depression is . What is the approximate horizontal distance from the observatory to the island?
A. 70 feet
B. 166 feet
C. 322 feet
D. 355 feet
Answer:
C
Step-by-step explanation:
We want to find the horizontal distance from the observatory to the island, which is adjacent to the known angle.
Because we also know the height of the observatory and is opposite to the angle, we can consider using tangent. Recall that:
[tex]\displaystyle \tan \theta ^\circ = \frac{\text{opposite}}{\text{adjacent}}[/tex]
Let the horizontal distance be x. Substitute in known values:
[tex]\displaystyle \tan 25^\circ = \frac{150}{x}[/tex]
Solve for x:
[tex]\displaystyle x = \frac{150}{\tan 25^\circ}[/tex]
Use a calculator. Hence:
[tex]x\approx 322\text{ feet}[/tex]
In conclusion, our answer is C.

Answer:
9.72 ft (nearest hundredth)
Step-by-step explanation:
The ramp is the hypotenuse of a right triangle = 10 ftThe ramp makes an angle of 18° with the horizontalLet b = the horizontal
First, calculate the horizontal distance [tex]b[/tex] by using the cosine trig ratio:
[tex]\cos(\theta)=\mathsf{\dfrac{adjacent\ side}{hypotenuse}}[/tex]
[tex]\implies \cos(18)=\dfrac{b}{10}[/tex]
[tex]\implies b=10 \cos(18)[/tex]
Given:
[tex]\theta[/tex] = 12°[tex]b=10 \cos(18)[/tex]The new ramp is the hypotenuse = hUse the cosine trig ratio to calculate the new hypotenuse:
[tex]\implies \cos(12)=\dfrac{10 \cos(18)}{h}[/tex]
[tex]\implies h=\dfrac{10 \cos(18)}{\cos(12)}[/tex]
⇒ h = 9.723036846...
⇒ h = 9.72 ft (nearest hundredth)
Answer:
14.86 feet
Step-by-step explanation:
We assume the new ramp arrives at the same height as the old one. That height is found using the sine function:
h = 10·sin(18°)
We want to find the ramp length x that will give the same height with an angle of 12°:
h = x·sin(12°)
Substituting for h, we get ...
10·sin(18°) = x·sin(12°)
x = 10·sin(18°)/sin(12°) ≈ 14.863 . . . . feet
The new ramp is about 14.86 feet long.

Additional comment
The sine relation is ...
Sin = Opposite/Hypotenuse
In this use, we rearrange it to ...
Opposite = Hypotenuse × Sin

Christian is 1.35 meters tall. At 10 a.m. , he measures the length of a tree’s shadow to be 38.65 meters. He stands 34.4 meters away from the tree, so that the top of his shadow meets the tip of the tree’s shadow. Find the height of the tree to the nearest hundredth of a meter.
The height of Christian and the height of the tree is a ratio likewise the length of Christian shadow and tree shadow. Therefore, the height of the tree to the nearest hundredth is 1.52 meters.
What is Proportion?Proportion is a mathematical comparison between two numbers. it says that two ratios (or fractions) are equal. Therefore,
Christian height = 1.35 m
Tree shadow = 38.65 meter
Christian shadow = 34.4 meters
Let's establish the proportion to find the height of the tree. Therefore,
let
x = height of the tree
1.35 / x = 34.4 / 38.65
cross multiply
38.65 × 1.35 = 34.4x
x = 52.1775 / 34.4
x = 1.5167877907
x = 1.52 meters
Therefore, The height of the tree is 1.52 meters.
