The triangle in the image is a right triangle. We are given a side and an angle, and asked to find another side. Therefore, we should use a trigonometric function.
Trigonometric Functions: SOH-CAH-TOA
---sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, tangent = opposite/adjacent
In this problem, looking from the angle, we are given the adjacent side and want to find the opposite side. This means we should use the tangent function.
tan(40) = x / 202
x = tan(40) * 202
x = 169.498
x (rounded) = 169 meters
Answer: the tower is 169 meters tall
Hope this helps!
Answer:
170 meters
Step-by-step explanation:
The three sides of a right triangle are named hypotenuse, adjacent side and opposite side and the angle the adjacent side makes with they hypotenuse is θ (see Figure 1)
In this description the terms
Opposite --> side opposite to the angle θ
Adjacent --> side adjacent to the angle θ
Hypotenuse --> longest side of the right triangle
The relationship between the ratio of the shorter sides and and the angle θ in the figure is given by the formula
[tex]\mathrm {\tan(\theta) = \dfrac{Opposite \; side}{Adjacent \;side}}[/tex]
We can view the Eiffel Tower as the opposite side, the distance from the base to the surveyor location as the adjacent side (see the second figure)
If we let h = height of the Eiffel Tower in meters , opposite side length = h m
The adjacent side length = 202 meters
The angle θ = 40°
Applying the tan formula we get
[tex]\tan(40^\circ) = \dfrac{h}{202}\\\\\textrm{Multiplying both sides by 202, }\\202 \tan(40^\circ) = h\\\\\\h = 202 \tan(40^\circ) \\\textrm{Using a calculator we get}\\\\h = 169.5\; meters[/tex]
Rounded to the nearest meter, the height = 170 meters

Are 12/7 and 36/21 proportional
Answers
Answer:
Step-by-step explanation:
Cross multiply:
12 * 21 = 7 * 36
Simplifying
12 * 21 = 7 * 36
Multiply 12 * 21
252 = 7 * 36
Multiply 7 * 36
252 = 252
Add '-252' to each side of the equation.
252 + -252 = 252 + -252
Combine like terms: 252 + -252 = 0
0 = 252 + -252
Combine like terms: 252 + -252 = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
(hope this helps can i plz have brainlist :D hehe)
From the calculations below, 12/7 and 36/21 are proportional, therefore, the statement is true.
The first fraction given is 12/7.
The second fraction given is 36/21.
In order to check, we can multiply both the numerator and the denominator by 3. This will be;
= (12 × 3) / (7 × 3)
= 36 / 21
Therefore, it has been solved that 12/7 and 36/21 are proportional.

How do I round 31732.441804 to the nearest dollar?
Answers
Answer and Step-by-step explanation:
To round to the nearest dollar, you are essentially rounding to the nearest whole number.
This involves looking at the tenths place.
31732.441804
The bolded 4 is in the tenths place (after the decimal), and determines if the number to the left of it rounds up or stay the same.
Since 4 is not greater than or equal to 5, it makes the number stay 2.
So, we get the answer to be $31732.

A meteorologist found that the rainfall in Campbell during the first half of the month was 3/10 of an inch. At the end of the month, he found that the total rainfall for the month was 1/2 of an inch. How much did it rain in the second half of the month?
Answers
Answer: 1/5
Step-by-step explanation:
Let the amount of rainfall in the second half of the month be represented by x.
From the information given in the question, the equation formed will be:
3/10 + x = 1/2
x = 1/2 - 3/10
x = 5/10 - 3/10
x = 2/10
x = 1/5
Therefore, the answer is 1/5

Step-by-step explanation:
✔️First, solve for r:
r/2 ≤ 3
Multiply both sides by 2
r/2 × 2 ≤ 3 × 2
r ≤ 6
This implies that possible value of r is equal to 6 or less than 6.
Graphing this on a number line, the line with a shaded circle, indicating that 6 is included, starts at 6 and points to the left.
This indicates that value of r ranges from 6 and below.
The graph is C.
