The length of the guy wire supporting a cell tower is 120 m. The guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?
Answer:
89.44m
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
This is given as:
Hypotenuse² = Opposite ² + Adjacent ²
Hypotenuse = Length of the guy wire = 120m
Adjacent = Distance from the base of the tower = 80m
Opposite = Height of the building = x
Hence:
120² = x² + 80²
Collect like terms
x² = 120² - 80²
x = √120² - 80²
x = √(8000)
x = 89.4427191 m
Approximately the height of the tower is = 89.44m

A blueberry muffin recipe calls for 3/4 cup of
sugar. How many cups of sugar would be
needed to make the muffin recipe 3 times?
Answer:
9/4 or 2 1/4 cups of sugar.
Step-by-step explanation:
To find the answer we multiply 3/4 by 3. Because the bottom stays the same, we wont multiply it. Since 3 x 3 = 9, it will be 9/4. Therefore, 9/4 or 2 1/4 is your answer.

Jane needs to fix a piece of broken siding on the side of her house. The top of the
ladder is placed is 8 feet high above the ground and the base of the ladder will be
placed 6 feet away from the house.
What is the length of the ladder? Round to the nearest whole number.
Answer:
The length of the ladder = 10 feet
Step-by-step explanation:
The ladder placed on the Wall forms a right angle triangle
Hypotenuse ² = opposite ² + adjacent ²
The top of the ladder = opposite
The base of the ladder = adjacent
The length of the ladder = hypotenuse
Opposite = 8 feet
Adjacent = 6 feet
Hypotenuse = ?
Hypotenuse ² = opposite ² + adjacent ²
= 8² + 6²
= 64 + 36
= 100
Hypotenuse ² = 100
Hypotenuse = √100
Hypotenuse = 10 feet
The length of the ladder = 10 feet

Find the indicated side of the
right triangle.
45°
у
6
45°
y = [?]/
Enter
Answer:
y = 6[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{y}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
y = 6[tex]\sqrt{2}[/tex]

in a school with 200 students, 45% are males. how many males are there.? please help me
Answer:
90 males.
Step-by-step explanation:
To find the answer we will divide 45% by 100, and we get 0.45. Now multiply 0.45 by 200 and you get 90. Therefore, 90 males is the answer.
slope that falls between (0,20) and (20,85)
Answer:
13/4
Step-by-step explanation:
To find the slope we use the equation
m= (y2-y1)/(x2-x1)
= (85-20)/(20-0)
= 65/20
= 13/4

ASAP! what type of angles are <3 and <10
A. Consecutive interior angles
B. Alternate exterior angles
C. alternative interior angles
D. Corresponding angles
Answer:
∠3 and ∠10 are;
B. Alternate exterior angles
Step-by-step explanation:
From the given diagram, we have;
∠3 and ∠10 are angles on the same transversal
The location of ∠3 and ∠10 are on the outer (exterior) part of the two lines crossed by the transversal that forms ∠3 and ∠10 such that the two lines comes between the angles
∠3 and ∠10 are on the alternate sides of the transversal such that ∠3 is below the transversal and ∠10 is above the transversal
Therefore, ∠3 and ∠10 are alternate exterior angles.
Marcel wants to buy a bike for 499$. he has already saved 256$. His grandma gives him 50$. He can save 12$ per month. How long does he have to wait before he can afford the bike?
Answer: 17 months

Answer:
add equation 2 from equation 3
Step-by-step explanation:
So, we are given equations 1, 2, and 3, but for this problem, we need to use just 2 and 3.
4x - 2y = -16
x + 2y = 6
In order to eliminate one variable, then we need to find whether there are two numbers that have the same coefficient (or multiply one by a number to make it) so that if you add/subtract two numbers, it gives you 0. So, in this problem, if you add
2y to -2y, then it gives you 0, which means that y would be canceled out.
So, the answer is the first option.
Feel free to ask any questions about clarity! (this explanation is pretty bad, but I can explain it more if you want) :D
Matsu walks 2 blocks west from the police station and then walks 3 blocks north. Give the coordinates of the place where he stops
The center is (2, 5) and the radius is 9
Give me work plsss
Answer:
[tex](x-2)^2+(y-5)^2=9^2[/tex]
Step-by-step explanation:
We use the equation
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Now we plug in the numbers
(h, k) = center point (2, 5)
This would equal
[tex](x-2)^2+(y-5)^2=9^2[/tex]
Circle B is shown. Line segments C B, D B, and E B are radii. Angle C B E is 52 degrees and angle E B D is 160 degrees. What is the measure of Arc C E D? 106° 108° 148° 212°
Answer:
212°
Step-by-step explanation:
The computation of the measure of Arc C E D is shown below:
= Angle EBD + Angle CBE
= 160 + 52
= 212 degrees
We simply added the angle EBD and Angle CBE so that the ARC CED could come
Therefore the last option is correct
Answer:
D. 212°
Step-by-step explanation:
Just took the quiz

Combined, Teresa and Janey have saved $345 dollars. Teresa has saved twice as much as Janey. How much money do they each have?
Answer: Janey has $115, and Teresa has $230.
Step-by-step explanation:
Set x be the money that Janey have, then Teresa have 2x.
x + 2x = 345
3x = 345
x= $115
2x= 2(115)= $230
