A key word to remember when doing this type of math is "SOHCAHTOA".

Sine =

Opposite over

Hypotenuse

Cosine =

Adjacent over

Hypotenuse

Tangent =

Opposite over

Adjacent


Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.

And the Hypotenuse would be simplified to 5.

So, the answer is 4 / 5!

Norma-Jean [14]

Answer:

  5956 ft

Step-by-step explanation:

If we designate the points at the bases of the skyscrapers as A and B, and the top of skyscraper B as point T, then triangle ABT is a right triangle with angle B = 90° and angle A = 13.7°.

The definition of the tangent function tells us ...

  tan(A) = BT/AB

Solving for AB, we find ...

  AB = BT/tan(A) = (1452 ft)/tan(13.7°)

  AB ≈ 5956 ft

The skyscrapers are about 5956 feet apart.

A scuba diver swam 96 feet beneath the surface of the lake . He then climbs up 49 feet. What is his depth now?
Iteru [2.4K]
If this question is as simple as it seems all you would have to do is subtract. If he is down 96 feet then goes up 49 feet you would do 96-49.

The answer is 47 feet.

I hope this helps! Let me know if this is right.

In printing an article of 48,000 words, a printer decides to use two sizes of type. Using the larger type, a printed page contai
9966 [12]

Answer:

17 pages

Step-by-step explanation:

Let L = number of pages printed Larger type

S = number of pages printed smaller type

 the article is allow 21 full pages in a magazine. -->L + S = 21

1,800L + 2, 400S = 48, 000 (we can divide 100 to make the math easier)

18L + 24S = 480

Solve:

L + S = 21

18L + 24S = 480

we can use elimination by eliminating 18L so we can isolate the value of S  

-18 (L + S = 21)

18L + 24S = 480

-18L - 18S = 378

18L + 24S = 480

6S = 102

S = 17
