(GIVING BRAINLIEST!!!)

AfilCa [17]

Answer:

$Total\ length = 8\frac{5}{8}\ miles$

Step-by-step explanation:

Given

See attachment for ski trails

Required

Total length of $2\frac{7}{8}$ ski trails

From the attached figure, there are 3 skis with length $2\frac{7}{8}\ miles$

So:

The total length is:

$Total\ length = 3 * 2\frac{7}{8}$

Express fraction as improper fraction

$Total\ length = 3 * \frac{23}{8}$

$Total\ length = \frac{3 *23}{8}$

$Total\ length = \frac{69}{8}$

$Total\ length = 8\frac{5}{8}\ miles$

Verify the pythagorean identity 1 + c o t ^2 θ = c s c ^2 θ

Grace [21]

Answer: The identity is verified. See the explanation.

Step-by-step explanation:

You must keep on mind the following identities:

$csc\theta=\frac{cos\theta}{sin\theta}\\\\csc\theta=\frac{1}{sin\theta}\\\\sin^2\theta+cos^2\theta=1$

Therefore, by substitution, you can rewrite the identity as shown below:

$1+cot^2\theta=csc^2\theta\\\\1+\frac{cos^2\theta}{sin^2\theta}=csc^2\theta$

Simpliying, you obtain:

$\frac{sin^2\theta+cos^2\theta}{sin^2\theta}=csc^2\theta\\\\\frac{1}{sin^2\theta}=csc^2\theta\\\\csc^2\theta=csc^2\theta$

The identity is verified.
