Elina [12.6K]

Answer:

X=20Tan(25)

Step-by-step explanation:

So because the cat is looking at the tree it is a strait line making a right triangle with the tree. The cat spots the bird 25 degrees up in the tree making a triangle. Then use SohCahToa, and because u have the adjacent side use Tangent because you are missing the opposite side of the angle. There are a few other ways to find it but that is the simplest way to perform this, GOOD LUCK!

Simplify (1/36)^n=216^n+5
Amanda [17]

Answer: - 2

Step-by-step explanation:

(1/36)^n = 216^n+5

(1/6^2)^n = (6^3)^n+5

(6^-2)^n = (6^3)^n+5

Opening the brackets

6^-2n = 6^3n+15

-2n = 3n + 15

collecting like terms

-2n - 3n = 15

-5n = 15

divide both sides by - 5

n = 15/-5

n = - 3
