Instructions: Find the measure of the indicated angle to the nearest degree.

sweet-ann [11.9K]

The measure of the indicated angle to the nearest degree is 47°.

<h3>What is the measure of the angle?</h3>

Given the data in the question;

Adjacent = 36
Hypotenuse = 53
Angle θ = ?

From trigonometric ratio, Cosθ = Adjacent / Hypotenuse

Cosθ = 36/53

θ = cos⁻¹( 36/53 )

θ = 47°

Therefore, the measure of the indicated angle to the nearest degree is 47°.

$\bf \cfrac{n^2+3n+2}{n^2+6n+8}-\cfrac{2n}{n+4}\implies \cfrac{n^2+3n+21}{(n+4)(n+2)}-\cfrac{2n}{n+4}
\\\\\\
\textit{so our LCD will just be (n+4)(n+2)}
\\\\\\
\cfrac{n^2+3n+2~~~~-~~~~(n+2)(2n)}{(n+4)(n+2)}
\\\\\\
\cfrac{n^2+3n+2~~~~-~~~~(2n^2+4n)}{(n+4)(n+2)}
\\\\\\
\cfrac{n^2+3n+2~~~~-~~~~2n^2-4n}{(n+4)(n+2)}
\implies 
\cfrac{-n^2-n+2}{(n+4)(n+2)}
\\\\\\
\cfrac{-(n^2+n-2)}{(n+4)(n+2)}\implies \cfrac{-\underline{(n+2)}(n-1)}{(n+4)\underline{(n+2)}}\implies \cfrac{-(n-1)}{n+4}\implies \cfrac{1+n}{n+4}$

kaheart [24]

Answer:

The given expression is a cubic polynomial with degree 3.

Step-by-step explanation:

We are given the following in the question:

$3x^3-x^2$

Polynomial:

A polynomial is an expression.
It consisting of variables and coefficients.
The variables and coefficients involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Since, the given expression satisfies all the properties, it is a polynomial.

Degree of polynomial:

It is the maximum degree of the polynomial.

The degree of given polynomial is 3.
