Greeley [361]3 years ago
7 0

Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in  the right triangle

sinΘ = \frac{opposite}{hypotenuse} = \frac{7}{9}, thus

Θ = sin^{-1}(\frac{7}{9}) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = \frac{opposite}{adjacent} = \frac{4}{5}, thus

Θ = tan^{-1}(\frac{4}{5}) ≈ 38.7°

Solve the rational equation 1/n-4 - 2/n = 3/4-n
Leokris [45]

Answer:

n=4

Step-by-step explanation:

Given equation: \[\frac{1}{n-4}-\frac{2}{n}=\frac{3}{4-n}\]

Simplifying the Left Hand Side of the equation by taking the LCM of the denominator terms:

\[\frac{n}{n*(n-4)}-\frac{2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]

=> \[\frac{n - 2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]

=> \[\frac{n - 2n + 8}{n*(n-4)}=\frac{3}{4-n}\]

=> \[\frac{8 - n}{n*(n-4)}=\frac{3}{4-n}\]

=> \[(8-n)*(4-n) =n*(n-4)*3\]

=> \[n-8 =3n\]

=> \[2n =8\]

=> n = 4
