The two men measure the angle of elevation to the highest point on the rock to be 22.6°. They
then walk 17 meters closer and measured the angle of elevation to be 38.3°. To the nearest meter,
how tall is Wave Rock?
You may not use Law or Sines to solve the problem.
Answers
Answer:
15 mStep-by-step explanation:
Refer to attached picture
The height = hAngles of elevation 22.6° and 38.3°Closer distance = dUse tangent to solve
tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79dCompare the equations above and find the value of d:
0.42(d + 17) = 0.79d0.42d + 7.14 = 0.79d0.79d - 0.42d = 7.140.37 d = 7.14d = 7.14/0.37d = 19.3 mNow find the value of h:
h = 0.79dh = 0.79*19.3h = 15Wave Rock is 15 m tall

how many yards
carpeting is needed to cover a 60 feet length room and 40 feet width
Answers
Answer:
[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]
Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].
[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]
3. Find the area of the room
Now multiply the length by the width to find the area of the room.
[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

Step-by-step explanation:
Two lines are parallel if they have the same slope.
the given equation is in the form
y=mx+b
where
m=-5/2
b=-7
m is the slope. You can see this by noting that if you increase x by 1 you increase y by m.
So, in this case, you are looking for a line with slope of -5/2.
You can solve each of the choice equations for y to see which one has the right slope.
A: y=(2/5)x-6 no good
B: y=-(2/5)x-1 no good
C: y=(5/2)x-4 no good
D: y=-(5/2)x-4 GOOD
So, I think the Knave of Spades is telling the truth because he wasn't accused of anything but im not sure. Brainliest goes to whoever answers the question properly :>
Answers
Answer:
B
Step-by-step explanation:
It all starts whether the Knave of Hearts tells the truth or not. You can decide yourself.
Hearts: H
Clubs: C
Diamonds: D
Spades: S
If H lies, C tells the truth, therefor D lies. So S tells the truth
If H tells the truth, C lies. Therefore D tells the truth and S lies
Answer:
2
Step-by-step explanation:
If the knave of hearts did steal the tarts, then the knave of clubs is lying saying that the knave of hearts is lying which mean the knave of diamonds is actually telling the truth when the knave of clubs said the knave of diamonds is lying they are therefore lying.
So in the question may be knave of hearts and Knave of diamonds may be telling the truth OR knave of clubs and knave of spades are telling the truth.

Given[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex]To find The value of the expressionSolutionLet's rewrite the given as:
[tex]\sqrt[3]{3\sqrt{21} + 8} - \sqrt[3]{3\sqrt{21} - 8}[/tex]Let the value is m and the expressions under 3rd roots are a and b, then we have
a = 3√21 + 8, b = 3√21 - 8m = ∛a - ∛bCube the both sides:
m³ = (∛a - ∛b)³m³ = a - b - 3[tex]\sqrt[3]{a^2b}[/tex] + 3[tex]\sqrt[3]{ab^2}[/tex]Simplify in bits:
a - b = 3√21 + 8 - 3√21 + 8 = 16ab = (3√21 + 8)(3√21 - 8) = 9*21 - 64 = 125∛ab = ∛125 = 5So the expression becomes:
