Looking north, two skyscrapers are sighted from the viewing deck of the Empire State Building at 1250 feet up. One skyscraper is sighted at a 20° angle of depression and a second skyscraper is sighted at a 30° angle of depression. How far apart are the two skyscrapers to the nearest foot?
Answers
Answer:
Step-by-step explanation:
The angle of depression is the angle between the line of sight and a vertical line.
The distance between the two skyscrapers is 1269ft
I've added as an attachment, a figure that illustrates the scenario
First, we calculate distance AB using the following tangent ratio
[tex]\mathbf{\tan(\theta) = \frac{Opposite}{Adjacent}}[/tex]
So, we have:
[tex]\mathbf{\tan(60) = \frac{AB}{1250}}[/tex]
Make AB the subject
[tex]\mathbf{AB = 1250 \times \tan(60)}[/tex]
Next, we calculate distance AC using the following tangent ratio
[tex]\mathbf{\tan(\theta) = \frac{Opposite}{Adjacent}}[/tex]
So, we have:
[tex]\mathbf{\tan(60+10) = \frac{AB + BC}{1250}}[/tex]
[tex]\mathbf{\tan(70) = \frac{AB + BC}{1250}}[/tex]
Make AB + BC, the subject
[tex]\mathbf{AB + BC = 1250 \times \tan(70)}[/tex]
Make BC the subject
[tex]\mathbf{BC = 1250 \times \tan(70) - AB}[/tex]
Substitute [tex]\mathbf{AB = 1250 \times \tan(60)}[/tex]
[tex]\mathbf{BC = 1250 \times \tan(70) - 1250 \times \tan(60)}[/tex]
[tex]\mathbf{BC = 1269}[/tex]
Hence, the distance between the two skyscrapers is 1269ft

Solve: 5(3x + 2) -2 = 2 (1 -7x)
Answers
Answer:
x=-6/29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+2)−2=2(1−7x)
(5)(3x)+(5)(2)+−2=(2)(1)+(2)(−7x)(Distribute)
15x+10+−2=2+−14x
(15x)+(10+−2)=−14x+2(Combine Like Terms)
15x+8=−14x+2
15x+8=−14x+2
Step 2: Add 14x to both sides.
15x+8+14x=−14x+2+14x
29x+8=2
Step 3: Subtract 8 from both sides.
29x+8−8=2−8
29x=−6
Step 4: Divide both sides by 29.
29x/29=-6/29
x=-6/29

Susan has 50% more books than Michael. Michael has 40 books. If Michael buys 8 more books, will Susan have more or less books than Michael? Use any method to solve the problem
Answers
Answer:
Susan has more books than Michael.
Step-by-step explanation:
If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael

You buy ten pizzas and pay with $100 how much change do you receive it the pizzas cost three for $25.50
Answers
Answer:
Step-by-step explanation:
3 vegetarian pizzas cost 25.50. First we must find the cost of one vegetarian pizza.
25.5/3 = 8.5.
Each pizza costs $8.50. She bought 10 of them.
Now, we must multiply $8.50 by 10.
8.5x10 = 85.
$85 for all of the pizza.
Finally, subtract 85 from 100.
100-85=15.
You will receive $15 in change.
Answer:
Should be $15 change
Step-by-step explanation:
Since 3 pizzas cost 25.50 you times that by 3. Divide the 25.50 by 3 and add them two together. Take away that from the 100
