Two buildings are 30 m apart. The angle from the top of the shorter building to the top of the taller building is. The angle from the top of the shorter building to the base of the taller building is. What is the height of the taller building?

Answers

Answer 1

Answer:

The height of the taller building is: 51.345m

Step-by-step explanation:

Given

The question has missing details (See attachment for the illustration of the complete question)

Required

The height of the tall building

The height, a, is calculated as:

[tex]a = b +c[/tex]

To solve for b, we consider the upper half of the attached image

The upper half is a right triangle.

Using tan formula, we have:

[tex]tan(31) = \frac{b}{30}[/tex]

Solve for b

[tex]b = 30 * tan(31)[/tex]

To solve for c, we consider the lower half of the attached image

Using tan formula, we have:

[tex]tan(48) = \frac{c}{30}[/tex]

Solve for c

[tex]c = 30 * tan(48)[/tex]

Recall that: [tex]a = b +c[/tex]

So:

[tex]a = 30 * tan(31) + 30 * tan(48)[/tex]

[tex]a = 30 * 0.6009 + 30 * 1.1106[/tex]

[tex]a = 18.027 + 33.318[/tex]

[tex]a = 51.345[/tex]

Answers

Answer:

b = 6

Step-by-step explanation:

here's your solution

=> 7/21 = b/18

=> by cross multiplication

=> 21b = 7*18

=> b = 126/21

=> b = 6

hope it helps

Answer:

b = 6

Step-by-step explanation:

To find the answer, find the GCF of 7 and 21, which is 7, and divide it by 7/7 to get 1/3, now the equation is 1/3 = b/18. How many times does 3 multiply to get 18? 6, multiply the first side of the equation by 6/6 to get 6/18, now we have 6/18 = b/18, since they are the same, b = 6

1/6 into a decimal and percent WILL REPORT AND GIVE BRAINLYEST

Answers

Answer:

1/6 = 0.167 or 16%

Step-by-step explanation:

Okay, so to go from a fraction to a decimal, you really just have to put the dot in the right place:

1/6 = 0.167 (rounded)

So 1/6 is 0.167 as a decimal

So to find the percentage:

0.167 x 10 = 16.7

So 1/6 is 16.7%

hope this helps:)

Answer:

Decimal: 0.166666667

Percent: 16.6666667%

Step-by-step explanation:

First a decimal:

Divide 1 ÷ 6: 0.166666667

Now a percent, to convert decimals to percents multiply them by 100 and add the percent sign:

0.166666667 ⋅ 100 = 16.6666667%

Answer:

∠ QRS = 100°

Step-by-step explanation:

Since RU bisects ∠ QRS , then

∠ QRU = ∠ SRU , that is

[tex]\frac{1}{2}[/tex] x + 10 = 50 ( subtract 10 from both sides )

[tex]\frac{1}{2}[/tex] x = 40 ( multiply both sides by 2 )

x = 80

Then

∠ QRU = [tex]\frac{1}{2}[/tex] x + 10 = 0.5 × 80 + 10 = 40 + 10 = 50°

∠ QRS = 50° + 50° = 100°

Adam bought a fish aquarium worth $2,000 in the first week of the year. Its value depreciates by 3% per
week. What will the value of fish aquarium after 5 weeks?

Answers

Answer:

The answer is 1825.35

Step-by-step explanation:

Since the first week isn’t included, we only count 4 weeks.

So first, 2000 x 0.03 = 60

(By the way 0.03 is 3%)

2000 - 60 = 1940

Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.

Then, week 3:

1940 x 0.03 = 58.2

1940 - 58.2 = 1881.8

Now, the last week, week four:

1881.8 x 0.03 = 56.45

1881.8 - 56.45 = 1825.35.

Therefore, 1825.35 after 5 weeks.
