Information for the park trails is displayed at the entrance to the park office.
Lisa [10]
So you can use tan here, which is opposite/adjacent. (We're looking for the Adjacent)

Since we know Trail E is 1700, we're looking for the patch of trail A that is the adjacent. So if we put 42 into a tan calculator we get about 0.9.

So that means that 1,700 / adjacent = 0.9.

So we can also say

1,700/0.9 = adjacent

or, 1,700/0.9 = 1888.89

Now, we have the little patch of trail A in the smaller right triangle. We want to find the patch of trail A in the larger right triangle.

So just do 5,000 - 1,888.89

You get 3111.11

So if we know that's that, and we're looking for the hypotenuse, or Trail B, we can use cosine, because that's adjacent / hypotenuse.

So 42 in a cosine calculator is 0.74 ish.

So 3111.11 / hypotenuse = 0.74

Or 3111.11 / 0.74 = hypotenuse

Or 3111.11 / 0.74 = 4204

So Trail C should be 4204 feet long.

The Rectangular rug has side lengths of 3 and 4 feet. What is the length of the diagonal?
lesya [120]

the formula to find the diagonal would be

a^2+b^2=c^2

3^2+4^2= 9+16=25

the square root of 25 is 5

5^2=25

so your diagonal is 5 ft

F(x)= x/5<br> Given the function f above, what is the value of f(100)?
Lera25 [3.4K]

Answer:

20

Step-by-step explanation:

f(x)= x/5

To solve for f(100), we substitute 100 for x everywhere in the equation:

f(100) = (100)/5

f(100) = 20
