<em>ANSWER:</em>

Add 8 and 5. You cannot add a number t a variable. So leave 4x+13 as the way it is.

Two sides of a triangle have the same length. The third side measures 3 m less than twice that length. The perimeter of the tria

Readme [11.4K]

Answer:

two sides have the length of 7m

third side is 11m

Step-by-step explanation:

perimeter is the sum of all sides

let 'n' = length of congruent sides

let '2n - 3' = length of third side

25 = n + n + 2n - 3

25 = 4n - 3

28 = 4n

n = 7m

2(7) - 3 = 11m

A terminal ray passes through (12,-5). Fine the value to all six trig functions

Harman [31]

Okay, here we have this:

Considering the provided angle, we are going to calculate the requested trigonometric functions, so we obtain the following:

So the first thing we will do is calculate the length of the hypotenuse, that is, the distance between the given point and the origin, then we have:

$\begin{gathered} r=\sqrt{(12-0)^2+(-5-0)^2} \\ r=\sqrt{12^2+(-5)^2} \\ r=\sqrt{144+25} \\ r=\sqrt{169} \\ r=13 \end{gathered}$

Now we proceed to find the value of each ratio:

$sin\beta=\frac{y}{r}=\frac{-5}{13}$ $cos\beta=\frac{x}{r}=\frac{12}{13}$ $tan\beta=\frac{y}{x}=\frac{-5}{12}$ $csc\beta=\frac{r}{y}=\frac{13}{-5}=-\frac{13}{5}$ $sec\beta=\frac{r}{x}=\frac{13}{12}$ $cot\beta=\frac{x}{y}=\frac{12}{-5}=-\frac{12}{5}$
