One angle of a triangle measures 16∘ more than the smallest, while a third angle is twice the smallest. Find the measure of each

PtichkaEL [24]

Answer:

Smallest angle: 41°

Second angle: 57°

Third angle: 82°

Step-by-step explanation:

Let's call the smallest angle as $x$

"while a third angle is twice the smallest": third angle is $2x$

"One angle of a triangle measures 16∘ more than the smallest": 2nd angle is $16+x$

We know sum of 3 angles in a triangle is 180 degrees, so we can set up the equation and solve for x:

$x+(16+x)+(2x)=180\\x+16+x+2x=180\\4x=180-16\\4x=164\\x=\frac{164}{4}=41$

So smallest angle is 41°

The 2nd angle is 16+41=57°

third angle is 2*41=82°

Find domain of the rational function C(x)=-x-5/x^2-25

iren2701 [21]

$\large\begin{array}{l} \textsf{Find the domais of the rational function:}\\\\ \mathsf{C(x)=\dfrac{x-5}{x^2-25}}\\\\\\ \textsf{Denominators can't be zero:}\\\\ \mathsf{x^2-25\ne 0}\\\\ \mathsf{x^2\ne 25}\\\\ \begin{array}{rcl} \boxed{\begin{array}{rcl}\mathsf{x\ne -5}&~\textsf{ and }~&\mathsf{x\ne 5}\end{array}} \end{array} \end{array}$

$\large\begin{array}{l} \textsf{So the domain of C is}\\\\ \mathsf{D_C=\{x\in\mathbb{R}:~~x\ne -5~~and~~x\ne 5\}}\\\\\\ \textsf{or using a more compact form}\\\\ \mathsf{D_C=\mathbb{R}\setminus\{-5,\,5\}}\\\\\\ \textsf{or in interval notation}\\\\ \mathsf{D_C=\left]-\infty,\,-5\right[\,\cup\,\left]-5,\,5\right[\,\cup\,\left]5,\,+\infty\right[\,.} \end{array}$

$\large\textsf{So pick up the one you prefer. They're equivalent ways}\\\textsf{to represent the domain.}$

Solve x/48 = 5/6 using two different strategies.

Anettt [7]

You can do this:
6 * ? = 48, ? = 8, so you multiply the five by 8 too, and you find that x = 40. Another method you can use would just to be to add 5 to the top and 6 to the bottom until the denominators equal each other.
